MAX3675

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. A lossof-lock (LOL) monitor is also incorporated as part of the fully integrated PLL. ____________________________Features o Single +3.3V or +5.0V Power Supply o Complies with ANSI, ITU, and Bellcore SDH/SONET Specifications o Low Power: 215mW at +3.3V o Selectable Data Inputs, Differential PECL or Analog o Received-Signal-Strength Indicator (RSSI) o Loss-of-Power and Loss-of-Lock Monitors o Differential PECL Clock and Data Outputs o No External Reference Clock Required MAX3675 ________________________Applications SDH/SONET Transmission Systems SDH/SONET Access Nodes Add/Drop Multiplexers ATM Switches Digital Cross-Connects Pin Configuration appears at end of data sheet. _________________Ordering Information PART MAX3675ECJ ...
