19-1258; Rev 2; 11/98 L MANUA ION KIT T A U L EVA BLE AVAILA 622Mbps, Low-Power, 3.3V Clock-Recovery and Data-Retiming IC with Limiting Amplifier _____________________ General Description The MAX3675 is a complete clock-recovery and dataretiming 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-signal analog levels. The analog inputs access the limiting amplifier stage, which provides both a received-signalstrength indicator (RSSI) and a programmable-threshold loss-of-power (LOP) monitor. Selecting the PECL amplifier disables the limiting amplifier, conserving power.
