As soon as the news came out, the whole country was in an uproar!

What?!

Japan is bullying us like this. As a central enterprise, your Aerospace Industry Corporation is still chasing others behind the butt and begging others to cooperate with each other?

The people immediately stopped doing it.

When we figured it out, the original partner of Aerospace Industry Corporation: Tesla Automobile in the United States has "reverse" Mitsubishi's 4g63 engine, and the performance of this engine with a model of 4l20 is even better than the Mitsubishi's original 4g63. Now it has entered the final stage of mass production, but the men of Aerospace Industry Corporation insisted on turning down the project that was about to be mass production, and tried their best to lick the Japanese's butts. The national sentiment was immediately aroused: What exactly do you Aerospace Industry Corporation want to do? Is your Aerospace Industry Corporation or our own company?

The Aerospace Industry Corporation was completely caught off guard by the sudden turn of public opinion. They never thought that the wave of anti-Japanese in China suddenly burned on their heads, and even felt a little aggrieved for a moment: We did nothing, okay?

But the people don’t care about this. They only know that Japan has bullied us since the late Qing Dynasty. It was not until 1945 that it was the case that Japan drove it out. The Japanese have committed a lot of blood debts on our territory. It’s only half a century. You guys have forgotten it? Fortunately, you have to be willing to boast about state-owned enterprises!

As for another person involved, Tesla Motors, no one thinks that Tesla Motors "learned" Mitsubishi's 4g63 engine is wrong. On the contrary, everyone's general view is: How much money and good things have you little Japanese taken from our homes for more than half a century? You won't compensate us if you defeated World War II. This is just to think that we will collect some interest first.

As for whether Tesla Motors "learned" to Mitsubishi engines is in line with international practices. Who cares about it? Anyway, everyone only knows that Tesla Motors vented its anger for us, that's a good thing - to put it off topic, after this incident, Tesla's image has been recognized by the people a lot.

For a time, the media was filled with calls for the Aerospace Industry Corporation to end their secret engagement with Mitsubishi Motors and honestly cooperate with Tesla Motors. The Aerospace Industry Corporation was under great pressure.

Although they knew that Lin Zheng must be making trouble behind this, the leaders of the Aerospace Industry Corporation were so angry that they had no choice but to do anything about Lin Zheng. They said what they wanted to end their cooperation with Tesla Motors. They said what they were preparing to cooperate with Mitsubishi Motors in Japan. They could not refuse to admit what they were saying, right?

As for Boss Lin Zheng, what was he doing at this time?

Well, Boss Lin is currently in the Electronics Research Institute, staring at the group's most heavyweight mobile phone in the second half of the year... to be precise, it is a mobile phone under development.

In Lin Zheng's definition, this is a semi-smart phone with GPRRS Internet access function, can be equipped with IQ mobile client and IQ Mu private cplayer player, and also has ja&va functions. Various practical ja&va software can be installed, which means that this phone can chat with IQ, listen to music, surf the Internet, and install various ja&va software. It is unceremonious to say that before the real smartphone was released, in terms of function, this phone is infinitely close to the smartphone at the beginning of the next century. The release of this phone will undoubtedly definitely kill all mobile phones on the world.

But now, Boss Lin is frowning: "What about the audio decoding solution? Why didn't I tell me if I removed the dac?"

"Mr. Lin, we think that having an MSA3507d decoding chip is enough. There is no need to use the dac. The decoding chip and the dac chip are too luxurious," Wang Bo, the project development engineer who hosted the phone, felt that there was no need to do this. It would be a shameful waste to use the dac: "If you put in more effort in tuning, the sound quality of this phone is about to catch up with the CD, and I don't think it is necessary."

Lin Zheng also knows that it is enough to have mas3507d. Mas3507d not only embeds the SPD SSPcore on a chip, but also inherits the power manager, program memory, clock manager, audio baseband processor, and has multiple interfaces such as i2s, i2c, and Pio. The powerful functions of this chip make it easy to complete MP3 audio decoding. From this perspective, there is indeed no need to use dac.

But Lin Zheng didn't think so, and shook his head and said, "No, DAC must, Wang Gong, do you remember the definition of this mobile phone when the group decided to launch this project?"

"Uh..." If Lin Zheng hadn't asked this question, Wang Bo would have forgotten it. Now Lin Zheng suddenly mentioned this, he couldn't remember it for a while. He frowned and thought for a while, and finally said with some uncertainty: "...Make the best mobile phone player with the best sound quality?"

"No," Lin Zheng shook his head: "It is a mobile phone with sound quality comparable to that of advanced CD players. Wang Gong, remember, sound quality! Sound quality is the first pursuit of this phone, and it is also the main core function of this phone. We have the best tuner in the industry. We have keenly grasped the future of the market. I don't want a product that is actually castrated. DAC must have, which is the previously determined solution of Mas3507d plus DAC3550a."

Lin Zheng insisted on using the dac and specified that he should use the dac3550a. There is of course a reason. This is not only because the sampling rate that the dac3550a can support from 8khz to 50khz, but also because the dac3550a has an internal oscillator and an integrated headphone amplifier. In the playback of mp3 music, it is equivalent to integrating the two parts of the playback structure's signal amplification and signal playback together to make the structure more compact. At the same time,

Not only is the high-quality multi-sampling rate DAC matching mas3507d, it integrates the last two parts of the mp3 playback structure, but also uses the unique multi-bit ∑△ technology of Mi Cronasintermetall to make the signal-to-noise ratio of D/A conversion reach an eye-catching 103db.

It can be said that dac3550a and mas3507d are simply a natural pair.

Having such a good "talent" is simply a waste of talent, which Lin Zheng absolutely cannot allow.

He was very annoyed, not only because of Wang Bo's own initiative, but also because Wang Bo almost delayed the group's entire product promotion plan... Fortunately, Lianchuang Technology has now established a complete scientific and reasonable R&D system. When Wang Bo insisted on removing the dac, this system alerted Lin Zheng.

"But... is it necessary?" Wang Bo hesitated: "I tried it. The difference between adding a dac and not adding a dac is very small. According to the analysis data of users who use CD and cassette Walkman provided by the group, users of these walkman products are in a relatively noisy environment for 70% of the usage time. Mas3507d is enough to provide them with good sound quality, and they cannot use a dac at all."

To be honest, Wang Bo's words are not unreasonable, but Lin Zheng patted his shoulder and smiled and said, "Mr. Wang, your idea is not wrong, but you think about the problem from the perspective of developers, not from the perspective of marketing personnel. There is a big difference between them."

"Hmm?" Wang Bo pushed his glasses, a little puzzled, and his eyes eagerly looking forward to Lin Zheng's explanation.

"The reason is actually very simple. When we promote the combination of decoding chip and dac, we can confidently tell our users that our mobile phones are no less than the current mainstream CD walkman products in terms of sound quality. Our decoding chip is mas3507d, and it is also equipped with a DAC chip with a signal-to-noise ratio of up to 103db..."

"But I'm afraid they don't understand these at all, right? How many people can understand what this number represents?" Wang Bo interrupted Lin Zheng's words, and his expression became more and more confused.

"Yes, they don't understand and don't know what this thing means at all, but it doesn't matter. As long as they think it's reasonable, it will be done. Just like when many people go to shopping in shopping malls, this function may not be useful, but since others have it, I must have it... This belongs to the category of consumer psychology."

Is that true? Wang Bo is a little confused, but he thought that his family seemed to do this when he went out to buy things. He would choose the most complete functions when buying products. Although many functions may not be used in his lifetime, it doesn’t matter. In the words of his wife, it is: "I know I can’t use them basically, but it doesn’t matter if I can’t use them. That’s my business. The problem is that it cannot be left out. What if I use them when I use them?"

So that's how it is.

Although some technicians can persist in their stubbornness, Wang Bo still understands one truth after all, that is, the product must serve the market and the company's profits. After understanding this, Wang Bo understood how much impact his previous stubbornness almost had on the company. His face turned red with shame: "Mr. Lin, I'm sorry, I almost..."

"It's okay, you are also trying to save costs for the company. I can understand this," Lin Zheng waved his hand to show that he was not angry. "But you made a mistake in the end, so you still have to punish you. Can you understand this?" (To be continued, please search for Astronomy, novels are better, updated and faster!
