The MAOM-037057 is a four channel 25.78 Gbps / 28.05 Gbps CDR with adaptive equalization and Externally Modulated Laser (EML) driver for use as a transmit device in 100 gigabit optical transceivers. The MAOM-037057 CDRs retime at 25.78 Gbps for 100GbE and EDR Infiniband, 27.95 Gbps for OTU4, and 28.05 Gbps for 32G Fiber Channel applications. Each channel includes adaptive input equalization, a high performance CDR, and an EML driver with adjustable output swing up to 2.5 Vpp. The CDR is reference-free and can be bypassed to support legacy or non-standard data rates. The MAOM-037057 is assembled in a 5.6 mm x 9.6 mm package and integrates diagnostic features such as PRBS31/9 pattern generator and PRBS31 error checker. The device is controlled through a 2-wire serial interface.
