The ADN2804 provides the receiver functions of quantization, signal level detect, clock and data recovery, and data retiming for 622 Mbps Ethernet, BPON ONT, SONET OC-12 WDM transponders, Regenerators/repeaters, Test equipment, Broadband cross-connects and routers.
The ADN2804 provides receiver functions for 622 Mbps NRZ data, including quantization, clock and data recovery, and data retiming. It automatically locks to the incoming data without an external reference clock and meets SONET jitter requirements. Typical applications include BPON ONT, SONET OC‑12, WDM transponders, test equipment, and broadband routers.
Key features include a single‑supply 3.3 V operation, 423 mW typical power consumption, LOS detection with adjustable threshold, and a compact 5 mm × 5 mm 32‑lead LFCSP package. The datasheet details specifications, pin configurations, timing diagrams, and design guidelines for both LVDS and LVTTL interfaces.
