622Mbps, Low-Power, 3.3V Clock-Recovery and Data-Retiming IC with Limiting Amplifier
General Description
The MAX3675 is a complete clock-recovery and datar e t i m i n g 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. 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

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

AC parameters are guaranteed by design and characterization. The MAX3675 is characterized with a PRBS of 223 - 1 maintaining a BER of 10-10 having a confidence level of 99.9%. A lower minimum input voltage of 2mVp-p is achievable; however, the LOP hysteresis is not guaranteed below 3.6mVp-p. Hysteresis = 20log(VRELEASE / VASSERT). Small-signal bandwidth cannot be measured directly. RSSI slope = [VRSSI2 - VRSSI1] / [20log (VID2 / VID1)]. 1UI = 1 unit interval = (622.08MHz)-1 = 1.608ns.
