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.

JITTER SPECIFICATIONS The ADN2816 CDR is designed to achieve the best bit-error- rate (BER) performance and to exceed the jitter transfer, generation, and tolerance specifications proposed for SONET/SDH equipment defined in the Telcordia Technologies specification. Jitter is the dynamic displacement ...

ADN2816 THEORY OF OPERATION The ADN2816 is a delay- and phase-locked loop circuit for clock recovery and data retiming from an NRZ encoded data stream. The phase of the input data signal is tracked by two separate feedback loops that ...

Page 13

At medium jitter frequencies, the gain and tuning range of the VCO are not large enough to track input jitter. In this case, the VCO control voltage becomes large and saturates, and the VCO frequency dwells at one extreme of ...

ADN2816 FUNCTIONAL DESCRIPTION FREQUENCY ACQUISITION The ADN2816 acquires frequency from the data over a range of data frequencies from 10 Mb/s to 675 Mb/s. The lock detector circuit compares the frequency of the VCO and the frequency of the incoming ...

ADN2816 Stop and start conditions can be detected at any stage of the data transfer. If these conditions are asserted out of sequence with normal read and write operations, they cause an immediate jump to the idle condition. During a ...
