The ADN2814 provides the receiver functions of quantization, signal level detect, and clock and data recovery for continuous data rates from 10 Mb/s to 675 Mb/s. The ADN2814 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.
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, loss-of-signal (LOS) detector circuit indicates when the input signal level has fallen below a user-adjustable threshold. The LOS detect circuit has hysteresis to prevent chatter at the output.
The ADN2814 is available in a compact 5 mm × 5 mm, 32-lead LFCSP.
