The ADN2807 provides the receiver functions of quantization, signal level detect, and clock and data recovery at rates of OC-3, OC-12, and 15/14 FEC. 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 native rates and 15/14 rate digital wrappers are supported by the ADN2807, 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 ADN2807 is available in a compact 7 mm × 7 mm 48-lead chip-scale package (LFCSP).
