ADN2811 OC-48/OC-48 FEC Clock and Data Recovery

The ADN2811 provides the receiver functions of quantization, signal level detect, and clock and data recovery at OC-48 and OC-48 FEC rates. 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 device is intended for WDM system applications and can be used with either an external reference clock or an on-chip oscillator with external crystal. Both the 2.48 Gbps and 2.66 Gbps digital wrapper rates are supported by the ADN2811, without any change of reference clock.

This device, together with a PIN diode and a TIA preamplifier, can implement a highly integrated, low cost, low power, fiber optic receiver.

The receiver front end signal detect circuit indicates when the input signal level has fallen below a user-adjustable threshold. The signal detect circuit has hysteresis to prevent chatter at the output.

The ADN2811 is available in a compact, 7 mm × 7 mm, 48-lead chip scale package.
