ADN2915

Data Sheet Continuous Rate 6.5 Mbps to 11.3 Gbps Clock and Data Recovery IC with Integrated Limiting Amp/EQ ADN2915 FEATURES GENERAL DESCRIPTION Serial data input: 6.5 Mbps to 11.3 Gbps No reference clock required Exceeds SONET/SDH requirements for jitter transfer/generation/tolerance Quantizer sensitivity: 7.3 mV typical (limiting amplifier mode) Optional limiting amplifier, equalizer, and bypass inputs Programmable jitter transfer bandwidth to support G.8251 OTN Programmable slice level Sample phase adjust (5.65 Gbps or greater) Output polarity invert Programmable LOS threshold via I2C I2C to access optional features The ADN2915 provides the receiver functions of quantization, signal level detect, and clock and data recovery for continuous data rates from 6.5 Mbps to 11.3 Gbps. The ADN2915 automatically locks to all data rates without the need for an external reference clock or programming. ADN2915 jitter performance exceeds all jitter specifications required by SONET/SDH, including jitter transfer, jitter generation, and jitter tolerance. The ADN2915 provides manual or automatic slice adjust and manual sample phase adjusts. Additionally, the user can select a limiting amplifier, equalizer, or bypass at the input. The equalizer is either adaptive or can be manually set. Loss of signal (LOS) alarm (limiting amplifier mode only) The receiver front-end loss of signal (LOS) detector circuit Loss of lock (LOL) indicator indicates when the input signal level has fallen b...
