+3.3V, 2.5Gbps Quad Limiting Amplifier

General Description

Features

The MAX3822 quad limiting amplifier is ideal for multi-

channel systems with data rates up to 2.5Gbps. The

MAX3822 operates from a single +3.3V supply, over

temperatures ranging from 0°C to +85°C. A channel-

select (CS) pin is provided to program single-, dual-, or

quad-channel operation. The disabled channels are

shut down to reduce power consumption. The output

interface for all four channels is CML.

o Single +3.3V Supply

o Single-, Dual-, or Quad-Channel Operation at

2.5Gbps

o 700mW Total Power Dissipation (Quad-Channel

Operation)

o 120ps Maximum Output Edge Speed

o Overall and Individual Channel Loss-of-Power

(LOP) Indicator

The input can be driven from 20mVp-p to 1000mVp-p

differentially. The threshold voltage control is common

for all four channels and is programmable by an exter-

nal resistor. Four separate power detectors are incorpo-

rated to monitor the received signal level for each

channel. Individual TTL-compatible loss-of-power (LOP)

indicators assert low if the channel signal input is below

the programmed threshold. Typically 4dB LOP hystere-

sis (2dB optical) is provided to prevent chattering when

the input signal level is close to the threshold. A general

LOP indicator is also provided which asserts low if one

or more of the four inputs is in the LOP condition.

o Differential CML Outputs with On-Chip Back

Termination Resistors

o 30ps Maximum Deterministic Jitter

o 2ps Random Jitter

o Power-Down Feature Shuts Down Unused

Channels

o Operating Temperature Range: 0°C to +85°C
