3.3 V 2.7 Gb/s

Limiting Amplifier

ADN2890

GENERAL DESCRIPTION

FEATURES

SFP reference design available

Input sensitivity: 3 mV p-p

80 ps rise/fall times

CML outputs: 700 mV p-p differential

Programmable LOS detector: 2 mV to 13 mV

Rx signal strength indicator (RSSI):

SFF-8472 compliant average power measurement

Single-supply operation: 3.3 V

The ADN2890 is a high gain, limiting amplifier optimized for

use in SONET, Gigabit Ethernet (GbE), and Fibre Channel

optical receivers that accept input levels of up to 2.0 V p-p

differential and have 3 mV p-p differential input sensitivity. The

ADN2890 provides the receiver functions of quantization and

loss of signal (LOS) detection. The ADN2890 can easily operate

at up to 3.2 Gb/s to support LX4 transceivers.

The limiting amplifier also measures average received power

based on a direct measurement of the photodiode current with

better than 1 dB of accuracy over the entire input range of the

receiver. This eliminates the need for external average Rx power

detection circuitry in SFF-8472 compliant optical transceivers.

Low power dissipation: 130 mW

Available in space-saving 3 mm × 3 mm 16-lead LFCSP

APPLICATIONS

SFP/SFF/GBIC optical transceivers

OC-3/12/48, GbE, Fibre Channel receivers

10GBASE-LX4 transceivers

WDM transponders

The ADN2890 limiting amplifier operates from a single 3.3 V

supply, has low power dissipation, and is available in a space-

saving 3 mm × 3 mm 16-lead lead frame chip scale package

(LFCSP).
