Limiting Amplifiers with Loss-of-Signal Detector

General Description

Features

The MAX3969 is a recommended upgrade for the

MAX3964 and MAX3968. The MAX3964A limiting amplifi-

♦ Single Supply: +3.0V to +5.5V

♦ 2mV Input Sensitivity

P-P

er, with 2mV

input sensitivity and PECL data outputs, is

P-P

♦ 1.2ns Output Edge Speed

ideal for low-cost ATM, FDDI, and Fast Ethernet fiber

optic applications.

♦ Loss-of-Signal Detector with Programmable

Threshold

The MAX3964A features 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 and complementary

PECL loss-of-signal (LOS) outputs, which indicate when

the power level drops below a programmable threshold.

The threshold can be adjusted to detect signal ampli-

tudes as low as 2.7mV . An optional squelch function

P-P

disables switching of the data outputs by holding them at

a known state during an LOS condition.

The MAX3968 provides the same functionality as the

MAX3964A, but has data-output edge speed suitable for

ESCON and 266Mbps fibre channel applications.

The MAX3964A/MAX3968 are available in die form, as

tested wafers, and in 20-pin QSOP packages. The

MAX3964AETP is available in a 20-pin thin QFN package.

♦ Analog Received-Signal-Strength Indicator

♦ Output Squelch Function

♦ Compatible with 4B/5B Data Coding
