Abstract
This paper introduces a four-channel photoelectric transceiver system-in-package. It has four-channel digital photoelectric transceiver, analog IF transceiver and signal processing functions. It integrates four-channel optical module, four-channel parallel ADC, four-channel synchronous DDS, static random access memory, two Falsh memories, crystal oscillator and NTC thermistor. Structurally, the ceramic integrated shell is used for high density integration, and its volume is less than 40 mm x 40 mm x 6 mm. The test results show that the bit error rate is 6.36E-13 at 6.25Gbps data rate, and the eye diagram is normal.
