FEATURES

PRODUCT DESCRIPTION

Serial data input: 12.3 Mb/s to 2.7 Gb/s

Exceeds SONET requirements for jitter transfer/

generation/tolerance

Quantizer sensitivity: 6 mV typical

Adjustable slice level: ±100 mV

Patented clock recovery architecture

Loss of signal (LOS) detect range: 3 mV to 15 mV

Independent slice level adjust and LOS detector

No reference clock required

Loss of lock indicator

I2C™ interface to access optional features

Single-supply operation: 3.3 V

The ADN2812 provides the receiver functions of quantization,

signal level detect, and clock and data recovery for continuous

data rates from 12.3 Mb/s to 2.7 Gb/s. The ADN2812 automati-

cally locks to all data rates without the need for an external

reference clock or programming. All SONET jitter requirements

are met, including jitter transfer, jitter generation, and jitter

tolerance. All specifications are quoted for −40°C to +85°C

ambient temperature, unless otherwise noted.

This device, together with a PIN diode and a TIA preamplifier,

can implement a highly integrated, low cost, low power fiber

optic receiver.
