M37047
Four channel 25G / 28G CDR with Integrated EML driver
The M37047 is a Four channel 25G / 28G CDR with Integrated EML driver for use as a transmit device in optical modules. The M37047 CDRs retime at 25.78 Gbps, 27.95 Gbps, and 28.05 Gbps. Each channel includes adaptive input equalization (optional programmable), a high performance CDR, and an EML driver with programmable output swing and crossing point. The CDR is reference-free and can be bypassed to support legacy or non-standard data rates. The M37047 is assembled in a 4 mm x 4.5 mm chip scale package (CSP) and integrates diagnostic features such as PRBS (31/9) generation and PRBS 31 error checking. The device core is powered from a single 1.8V supply and the EML driver is powered with 1.8V and 3.3V supplies, delivering industry’s leading low power consumption. The device is controlled through a 2-wire serial interface.
