Overview

1mV_P-P Input Sensitivity
Loss-of-Signal Detector with Programmable Threshold
TTL LOS and PECL Signal Detect

Analog Received-Signal-Strength Indicator
Output Squelch Function
Compatible with 4B/5B Data Coding

The MAX3969 limiting amplifier with PECL data outputs is ideal for low-cost ATM, Fast Ethernet, FDDI and ESCON fiber optic receivers.

The MAX3969 features 1mV_P-P input sensitivity and an integrated power detector that senses the input signal power. It provides a received-signal-strength indicator (RSSI), which is an analog indication of the power level. Signal strength is also indicated by the complementary TTL loss-of-signal (LOS) outputs and the PECL signal-detect (SD) output, both of which indicate the power level relative to a programmable threshold.

The threshold can be adjusted to detect signal amplitudes as low as 2.7mV_P-P. An optional squelch function disables switching of the data outputs by holding them at a known state when the signal is below the programmed threshold.

The MAX3969 is available in die form and a 4mm x 4mm, 20-pin thin QFN package.
