ADN2811,pdf,datasheet下载 Dual Rate Limiting Amplifier and Clock a-The ADN2811 prov
The ADN2811 provides receiver functions of Quantization, Signal Level Detect and Clock and Data Recovery at rates of OC-48 and the associated FEC rates. All SONET jitter requirements are met, including: Jitter Transfer; Jitter Generation; and Jitter Tolerance. All specifications are quoted for -40潞C to +85潞C ambient temperature unless otherwise noted.
The proprietary delay and phase-locked loop design of the ADN2811 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 ADN2811, without any change of reference clock required. 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.
