General Description
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 (
LOL
) output to
indicate whether the CDR is in lock. The recovered data
and clock outputs are CML with on-chip 50
back termi-
nations 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 -40°C to +85°C.
