622 Mbps Clock and Data Recovery IC

with Integrated Limiting Amplifier

ADN2804

FEATURES

GENERAL DESCRIPTION

Exceeds SONET requirements for jitter transfer/

generation/tolerance

Quantizer sensitivity: 3.3 mV typical

Adjustable slice level: 95 mV

Patented clock recovery architecture

Loss-of-signal (LOS) detect range: 2.6 mV to 18.4 mV

Independent slice level adjust and LOS detector

No reference clock required

The ADN2804 provides the receiver functions of quantization,

signal level detect, clock and data recovery, and data retiming

for 622 Mbps NRZ data. The ADN2804 automatically locks to

622 Mbps data without the need for an external reference clock

or programming. In the absence of input data, the output clock

drifts no more than 5%. 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.

Loss-of-lock indicator

I²C® interface to access optional features

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

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

optic receiver.

Single-supply operation: 3.3 V

Low power: 423 mW typical

5 mm × 5 mm, 32-lead LFCSP, Pb free

The receiver’s front-end loss-of-signal (LOS) detector circuit

indicates when the input signal level falls below a user-adjustable

threshold. The LOS detect circuit has hysteresis to prevent chatter

at the output.

APPLICATIONS

BPON ONT

SONET OC-12

WDM transponders

Regenerators/repeaters

Test equipment

The ADN2804 is available in a compact 5 mm × 5 mm,

32-lead LFCSP.
