ADN2865

www.DataSheet4U.com Continuous Rate 12.3Mb/s to 2.7Gb/s Clock and Data Recovery IC w/Loop Timed SERDES Preliminary Technical Data FEATURES Serial data input: 12.3 Mb/s to 2.7 Gb/s Exceeds ITU-T Jitter Specifications Integrated Limiting Amp: 6mV sensitivity Adjustable slice level: ±100 mV Patented dual-loop clock recovery architecture Programmable LOS detect and Slice Level Integrated PRBS Generator and Detector No reference clock required Loss of lock indicator Rate Selectivity without the use of a reference clock I2C™ interface to access optional features Single-supply operation: 3.3 V Low power: 1.0W 8 mm × 8 mm 56-lead LFCSP ADN2865 PRODUCT DESCRIPTION The ADN2865 provides the receiver functions of quantization, signal level detect, and clock and data recovery for continuous data rates from 12.3 Mb/s to 2.7 Gb/s. An integrated deserialiser supports 8 bit parallel transfer to an FPGA or digital ASIC. The recovered clock can simultaneously serialize data supplied in an 8 bit parallel format. The ADN2865 automatically locks to all data rates without the need for an external reference clock or programming. All SONET jitter requirements are exceeded, 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 ADN2865 have many optiona...
