Quad 25G / 28G CDR with Integrated Equalization and EML Driver

The MAOM-37051A is a 25/28Gbps CDR with an integrated EML driver designed to meet the stringent size and power consumption requirements of CFP4 and QSFP28 optical modules. This device integrates a high-performance quad channel 28Gbps CDR with a high output voltage driver which can drive EMLs and Silicon Photonics with voltages up to 2.5Vpp, allowing the MAOM-37051A to be used with the complete range of EMLs available on the market today. The quad channel, reference free CDR has adjustable rates to cover 100GbE, Infiniband, OTU4 and Fiber Channel applications while including adaptive input equalization and diagnostic features such as PRBS generator and error checker. The part is packaged in an 11mm x 7mm surface mount package and provides a low power EML based solution for small form factor optical modules.
