HX3010 is a single-channel transimpedance amplifier designed for optical transmission systems at data rate from 8.5Gbps up to 28.1Gbps.The HX3010 can be integrated into a ROSA package together with a photodiode. It provides the bias voltages to the photodiode and converts the photo current from photodiode into a differential output voltage. It is internally integrated with limiting amplifier, automatic gain control circuit and average photocurrent monitoring circuit (RSSI).

• 25Gbps Ethernet

• Next-Generation CPRI

• SFP28 Optical Modules

HX3210E is the upgraded version of HX3210. HX3210E integrates the OAM function on the basis of HX3210, and is the first electronic chip integrating the OAM standard of three major operators in the market. 

HX310E integrates the function of physical layer, link layer and part of service layer. The TX direction integrates packet grouping, CRC calculation, automatic insertion of idle packets, automatic repeat sending, manchester coding, modulation and other functions. RX direction integrates demodulation, manchester decoding, byte delimitation, frame delimitation, CRC verification, synchronous state machine control and other functions. The high integration of HX3210E makes it possible to achieve the OAM function without other components which greatly reduces the development difficulty of module manufacturers and greatly simplifies the production and debugging work. The user can config the register to support the standard of MWDM, LWDM and DWDM respectively.
