DWDM and SONET/SDH applications. A 4
鉁?/div>
4-bit FIFO
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
circuitry, and delivers current-mode logic (CML) serial
data and clock outputs. A loopback data output is pro-
vided to facilitate system diagnostic testing. The
MAX3892 is available in the extended temperature
range (-40掳C to +85掳C) in a 44-pin QFN package.
