_____________________ General Desc ription
The MAX3675 is a complete clock-recovery and data-
retiming IC incorporating a limiting amplifier. It is
intended for 622Mbps SDH/SONET applications and
operates from a single +3.3V supply.
The MAX3675 has two differential input amplifiers: one
accepts PECL levels, while the other accepts small-sig-
nal analog levels. The analog inputs access the limiting
amplifier stage, which provides both a received-signal-
strength indicator (RSSI) and a programmable-threshold
loss-of-power (LOP) monitor. Selecting the PECL amplifier
disables the limiting amplifier, conserving power. A loss-
of-lock (LOL) monitor is also incorporated as part of the
fully integrated PLL.
