At the same time, Shanghai Belling adc chip is growing steadily, which is very worthy of optimism.
More than 90% ADC in China is monopolized by the United States.
ADC is a kind of signal chain chip in analog chip subdivision circuit, accounting for about 15% of the analog chip market, and it is also the part with the highest difficulty coefficient.
The performance of ADC chip mainly depends on sampling rate and conversion accuracy, and what is important is "high speed and high accuracy".
For example, Yadeno's sampling rate reaches 26G per second and its accuracy reaches 32 bits.
From the perspective of domestic ADC manufacturers, on the one hand, there is a huge room for improvement in speed and accuracy compared with foreign giants.
On the other hand, bibcock has the advantage of technology first-Mover, among which Shanghai Beiling has the fastest sampling rate, reaching 125M per second, and its accuracy reaches 14, which is second only to that of Shengbang.
Therefore, Shanghai Beiling ADC products are mainly used in Beidou navigation, signal reception, medical imaging and other fields that require high speed and accuracy.
The 2020 annual report shows that the ADC products of Shanghai Belling have been sold in small batches in these fields.
202 1 interim report shows that Shanghai belling has further expanded its high-speed and high-precision ADC and DAC business, and related products have been successfully designed and imported in the fields of electric power, industrial control and rail transit.
It can be seen that ADC products have higher barriers, fewer competitors and smooth business development, which is expected to become an important growth point of Shanghai Belling in the future.
