MAX3873A Low-Power, Compact 2.5Gbps/2.7Gbps Clock-Recovery And Data-Retiming IC

The MAX3873A is a compact, low-power 2.488Gbps/2.67Gbps clock-recovery and data-retiming IC for SDH SONET applications. The phase-locked loop (PLL) recovers a synchronous Clock signal from the serial NRZ data input. The input data is then retimed by this recovered Clock providing a clean data output. The MAX3873A meets all SDH SONET jitter specifications, does not require an external reference Clock to aid in frequency acquisition, and provides excellent tolerance to both deterministic and sinusoidal jitter. The MAX3873A provides a PLL loss-of-lock (active-low LOL) output to indicate whether the CDR is in lock. The recovered data and Clock outputs are CML with on-chip 50 back terminations on each line. The Clock output CAN be powered down if not used.
The MAX3873A is implemented in Maxim's second-generation SiGe process and consumes only 260mW at 3.3V supply (output Clock disabled, low output swing). The device is available in a 4mm x 4mm 20-pin QFN exposed-pad package and operates from -40C to +85C.
