622 Mbps Clock and Data Recovery IC
ADN2806
GENERAL DESCRIPTION
The ADN2806 provides the receiver functions for clock and
data recovery, and data retiming for 622 Mbps NRZ data. The
ADN2806 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.
This device, together with a PIN diode, TIA preamplifier, and a
lim amp can implement a highly integrated, low cost, low power
fiber optic receiver.
The ADN2806 is available in a compact 5 mm × 5 mm,
32-lead LFCSP.
