Continuous Rate 12.3 Mb/s to 2.7 Gb/s Clock and

Data Recovery IC with Integrated Limiting Amp

Data Sheet

ADN2812

FEATURES

GENERAL 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

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 auto-

matically 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.

Loss of lock indicator

I²C interface to access optional features

Single-supply operation: 3.3 V

The receiver front end, loss of signal (LOS) detector circuit

indicates when the input signal level has fallen below a user-

adjustable threshold. The LOS detect circuit has hysteresis to

prevent chatter at the output.

Low power: 750 mW typical

5 mm × 5 mm 32-lead LFCSP

APPLICATIONS

SONET OC-1/OC-3/OC-12/OC-48 and all associated FEC rates

Fibre Channel, 2× Fibre Channel, GbE, HDTV

WDM transponders

The ADN2812 is available in a compact 5 mm × 5 mm 32-lead

lead frame chip scale package (LFCSP).
