The ADN2819 provides receiver functions of quantization, signal level detect and clock and data recovery at rates of OC-3, OC-12, Gigabit Ethernet, OC-48 and all FEC rates. All SONET jitter requirements are met, including jitter transfer, jitter generation and jitter tolerance. All specifications are quoted for -40ºC to +85ºC ambient temperature unless otherwise noted.
The proprietary delay and phase-locked loop design of the ADN2819 provides unprecedented jitter performance for robust high-speed networking designs.
The device is intended for WDM system applications and can be used with either an external reference clock or an on-chip crystal oscillator. Both native rates and 15/14 rate digital wrappers rates are supported by the ADN2819, without any change of reference clock required. This device together with a PIN diode and a TIA preamplifier can implement 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.
