Yang Minghui is now more and more unable to understand his son in front of him: "Then let's wait until you design it." He also had no hope for it.

Zhang Yujie looked at Yang Jie and asked in shock: "Dude, do you really want to design a chip?"

"Of course, since I've said such things in front of my dad now, if I hadn't designed it, where would I have my face!"

Yang Jie said with a smile: "Only after I design this chip can this solve the dilemma that my father's electronics factory is facing now." ”

"What do you say?" asked Zhang Yujie suspiciously.

Yang Minghui also looked at Yang Jie at this time, and he also wanted to hear what his son could say.

"Now the country is vigorously promoting digital telephones, the country will definitely cancel the initial installation fee of telephones, when the number of digital telephones installed will definitely soar, we have a population of 1.3 billion in China, is the largest market in the world, the number of digital telephones installed in the next few years will be at least tens of millions of units every year, if Huayue Electronics Factory helps me to produce, as long as the cost of producing chips is lower than the cost of foreign chips, how to sell millions, according to each chip 20 yuan to calculate, the annual income of the electronics factory can reach tens of millions。 ”

Yang Minghui's face was moved: "How do you know that the chip you designed will definitely be stronger than the foreign digital phone chip?"

"Dad, didn't I say it, you'll know when I'm done. Yang Jie said with a smile: "If I am a son, can I still pit you, your old son?"

Yang Minghui couldn't cry or laugh: "If the chip you designed is really as good as you say, the electronics factory will immediately help you test the tape-out." ”

Yang Jie was overjoyed, he knew that this was half of the success.

"Dude, you're going to do the chip design now?" Zhang Yujie couldn't believe it anyway.

"It's not that hard. Yang Jie said.

Just kidding, as the world's top IC design and manufacturing scientist in his previous life, he couldn't even handle a single-chip digital phone chip, isn't that an international joke!

At this time, it was already more than nine o'clock in the evening, and Zhang Yujie didn't plan to go back, so he went to Yang Jie's house with Yang Jie.

Seeing the familiar old buildings around him, Yang Jie felt an inexplicable emotion in his heart, and his eyes were a little astringent.

"Xiaojie, why did you come back with your father?" asked her mother, Cai Wenya, in surprise when she saw her husband and son coming back together.

"My son did a great favor in the factory at night. Yang Minghui said.

"How can my son help?" Cai Wenya looked at Yang Jie suspiciously.

"Auntie, Yang Jie, he's amazing!" Zhang Yujie said with a smile.

"What the hell is going on?" Cai Wenya asked Yang Minghui.

"Mom, don't ask, Zhang Yujie and I didn't eat anything in the afternoon, is there any leftover food at home?"

"I'll get it for you two. Cai Wenya said with a smile.

After eating, Zhang Yujie told Yang Jie everything he did today, but he was even more excited than Yang Jie.

"Son, why did you suddenly become so powerful?"

"Mom and Dad, you work so hard, if I don't work hard, won't I be sorry for you? Yang Jie said.

"You're too big a kid. Yang Minghui said with emotion.

After Yang Jie and Zhang Yujie returned to their bedroom, the latter still looked excited: "Yang Jie, you usually hide deep enough, today you really opened my eyes!"

Zhang Jie threw a change of clothes to him: "Go take a shower, I don't want to sleep in the same bed with you who stinks." ”

Zhang Yujie immediately hummed a song and went to the bathroom next to him to take a bath.

At this time, Yang Jie began to think about the solution of digital phone chips.

He knows that Huaxia is now vigorously promoting the development of digital telephones, and there are almost more than 300 telephone factories in the country, of which 160 have been approved by the Ministry of Posts and Telecommunications to access the network, and the rest are small copycat factories that commit crimes against the wind.

Compared with the latest magnetic card telephones, video phones, IC card telephones, voice-activated telephones, mother-child telephones, etc., domestic manufacturers have a single product, low-end technology, obsolete and rough technology, and high failure rate, so they cannot form a competitive advantage in the market.

Wealthy people in China are more inclined to use imported telephones, such as Siemens, Philips, Alcatel, Sony, Panasonic and other foreign brands, although the price is expensive, but the quality is much better than the domestic ones.

Yang Jie's own home is his home is the joint venture brand of TCL production of the mother and child machine, in the post and telecommunications bureau to install the telephone selection machine, the telephone selection fee reached more than 800 yuan, this is two years ago installed.

He vividly remembered that in 1995 there were 800 million telephones in the world, and a few developed countries in Europe, the United States and Japan accounted for more than 80 per cent of them, but their population was only 16 per cent of the world's population.

There are 1.3 billion people in China, and there will be countless enterprises in the future.

Therefore, he is full of confidence in the commercial future of the digital telephone master control chip he is designing.

At present, the digital telephones assembled by those joint ventures in China are all chips developed by AMS in Australia, which are sold by the general agent of Hong Kong Demaofeng.

This chip was designed in 94, in addition to supporting ringing, dialing, calling, and storing 31 number functions, it does not support LCD display control, nor does it support the basic functions of telephones such as caller ID that can be seen everywhere in later generations.

It is this chip, whose 20-year patent period means monopoly sales, and now it basically occupies a very large market share

This chip is batched at a minimum of 1,000 pieces, with an import price of 3.5 US dollars per piece, which is equivalent to 30 yuan a piece according to the current RMB exchange rate, but the manufacturing cost of only a few cents is almost negligible.

But now Huaxia Kingdom can neither design nor have relevant chip patents, so it can only be imported with a pinching nose!

And Chinese phone manufacturers, using it to assemble, produce and sell a phone, work hard but only make a dozen yuan from the whole machine.

This is the difference between a manufacturing power and a manufacturing power, one is to easily lie down and eat a large piece of meat, the other is tired and tired to drink soup, the difference is that one has core technology and patents, and the other does not.

Moreover, the chip has been inspected and certified by the National Telephone Quality Supervision and Inspection Center, which is equivalent to indirectly encouraging domestic imports of this relatively cheap telephone chip.

In 94 years, there were 38 million telephones in China, and in 95 years, it increased to 44 million units, in the next few years, with the beginning of the domestic exchange, the initial installation fee of the telephone avalanche generally declined, and the future domestic market will have more than 10 million telephones per year.

Yang Jie roughly estimated, this means that Australia's AMS company and its foundry Austrian Austrian Microelectronics, as well as the sales agent Hong Kong Demaofeng, will earn tens of millions of dollars on this chip every year in the future.

This situation lasted until 2003, when IC companies in Taiwan and mainland China began to enter the field of telephone chip design and manufacturing, and the wholesale price of the chip fell all the way to less than one yuan.

As long as Huayue Electronics Factory helps me tape-out, test, and produce, after the large-scale production of this thing, the cost is only a few cents, and the current process technology of Huayue Electronics Factory is completely sufficient.

Thinking of this, Yang Jie's heart suddenly became hot, and he began to think about the design drawings of the digital phone chip suitable for the process production of Huayue Electronics Factory.

Now that he has promised to help test tape-outs, there is no need to worry about how to find a suitable wafer factory to foundry.

And now Huayue Electronics Factory is OEM chips for Huatai Company, and after designing the digital phone chip, it is possible to authorize Huatai Company through his father's relationship, and Huatai Company is his first customer.
