FEATURES Serial data input: 10 Mb/s to 1.25 Gb/s Exceeds SONET requirements for jitter transfer/ generation/tolerance Patented clock recovery architecture No reference clock required Loss-of-lock indicator I2C® interface to access optional features Single-supply operation: 3.3 V Low power: 390 mW typical 5 mm × 5 mm 32-lead LFCSP, Pb free APPLICATIONS SONET OC-1/-3/-12 and all associated FEC rates Fibre Channel, GbE, HDTVs WDM transponders Regenerators/repeaters Test equipment Broadband crossconnects and routers GENERAL DESCRIPTION The ADN2815 provides the receiver functions of quantization and clock and data recovery for continuous data rates from 10 Mb/s to 1.25 Gb/s. The ADN2815 automatically locks to all data rates without the need for an external reference clock or programming. 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 ADN2815 is available in a compact 5 mm × 5 mm 32-lead LFCSP.
