USES the kernel architecture (M0, has the largest 64 k Flash + 8 k RAM, the highest working frequency is 64 MHZ, contains the rich peripherals,
The built-in 16-bit resolution of PWM, support multiple input capture; Contains rich communication interface,
All the way from the I2C interface to the hardware, support 100 k, 400 k, 1 m, 4 m BPS, support four seven reply from the address register, whether can be set to produce responses, support response a clock extension;
Synchronous and asynchronous, half duplex serial interface, support 4 ~ 16 bit master-slave SPI, cache depth is 4; Four configurable logical unit without the CPU can run by itself; High performance two rail to rail op-amp;
High precision 1 MHz 12 bit ADC conversion speed; Built-in high accuracy +/- 1 degree of temperature sensor,
Operating voltage: 2.2 V ~ 3.6 V,
There are three kinds of packaging forms: QFN32 QFN24, QFN20,
Light module is mainly used manufacturer:
Optical communication industry chain as shown in the figure below:
Rate under 10 g optical module, domestic manufacturers have completed from the chip to the module of domestic alternative; 40 g/10 g/25 g/100 g light module, optical communications technology ZhongJi solectron, hisense broadband, south China university of technology is the source, such as domestic manufacturers have achieved full range of products covering, module design and packaging process maturity; 400 g optical module, ZhongJi solectron, optical communications technology, hisense broadband, new Yi Sheng have been launched in OFC2018 samples and solutions,
Higher rate:
Light module rate ascension has two kinds of methods, one is to improve the rate of bits per channel, the second is to increase the number of channel, with the promotion of technology, baud rate, single channel of ascension is becoming increasingly difficult, 10 g of ascension is to 40 g channel number, 40 g to 100 g of ascension is the baud rate of single channel, and 100 g to 400 g, if just ascending channel number, is the 16 x 25 g solution, if the ascending channel bit rate is 4 * 100 g solution, in terms of the current technology to do 100 g baud rate have bottleneck, 50 g is difficult, but also can be realized, thus need higher modulation way,
