Continuous Rate 10 Mb/s to 675 Mb/s
Clock and Data Recovery IC
Data Sheet
ADN2816
FEATURES
GENERAL DESCRIPTION
Serial data input: 10 Mb/s to 675 Mb/s
Exceeds SONET requirements for jitter transfer/
generation/tolerance
Patented clock recovery architecture
No reference clock required
Loss-of-lock indicator
I2C® interface to access optional features
Single-supply operation: 3.3 V
Low power: 366 mW typical
The ADN2816 provides the receiver functions of quantization
and clock and data recovery for continuous data rates from
10 Mb/s to 675 Mb/s. The ADN2816 automatically 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.
5 mm × 5 mm 32-lead LFCSP, Pb free
The ADN2816 is available in a compact 5 mm × 5 mm 32-lead
LFCSP.
APPLICATIONS
SONET OC-1/-3/-12 and all associated FEC rates
Fibre Channel, ESCON, Fast Ethernet, SDI
WDM transponders
