The MAX3892 serializer is ideal for converting 4-bit-
wide, 622Mbps parallel data to 2.5Gbps serial data in
DWDM and SONET/SDH applications. A 4
allows for any static delay between the parallel output
clock and parallel input clock. Delay variation up to a
unit interval (UI) is allowed after reset. A fully integrated
phase-locked loop (PLL) synthesizes an internal
2.5GHz serial clock from a 622MHz, 155.5MHz,
77.8MHz, or 38.9MHz reference clock. A selectable
dual VCO allows excellent jitter performance at both
SONET and forward-error correction (FEC) data rates.
Operating from a single 3.3V supply, this device
accepts low-voltage differential-signal (LVDS) clock and
data inputs for interfacing with high-speed digital circuit-
ry, and delivers current-mode logic (CML) serial data
and clock outputs. A loopback data output is provided
to facilitate system diagnostic testing. The MAX3892 is
available in the extended temperature range (-40°C to
+85°C) in 44-pin QFN and TQFN packages.
