GENERAL DESCRIPTION
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.
The ADN2816 is available in a compact 5 mm × 5 mm 32-lead
LFCSP.
