ADN2819ACP-CML

Overview

The ADN2819ACP-CML is a multirate clock and data recovery IC with an integrated limiting amplifier, designed for SONET/SDH applications. It operates at rates up to 2.7 Gbps, supporting OC-3, OC-12, OC-48, Gigabit Ethernet, and 15/14 FEC standards. The device features CML differential inputs and outputs, a single-supply voltage range of 3V to 3.6V, and typical power dissipation of 540 mW. It includes a quantizer sensitivity of 4 mV p-p, adjustable slice levels, and loss-of-signal detection. Packaged in a 48-lead LFCSP (7 mm × 7 mm), it meets SONET jitter requirements.

Feature Summary

• Multirate operation from 155 Mbps to 2.7 Gbps including 15/14 FEC wrapper rates
• Integrated limiting amplifier with 4 mV typical input sensitivity
• Supports external reference clocks or on-chip oscillator with external crystal
• Complies with SONET jitter transfer, generation, and tolerance specifications

Applications

• SONET OC-3/-12/-48 and SDH STM-1/-4/-16 systems
• Gigabit Ethernet receivers
• WDM transponders and regenerators/repeaters
• Backplane applications and test equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Confirm availability status as supply conditions may vary. Ensure compatibility with system voltage and interface requirements before procurement.

Selection Notes

Select based on required data rate support, specifically if 15/14 FEC rates are needed. Verify reference clock source availability, as the device supports both external REFCLK and internal oscillator configurations. Check thermal management requirements given the 540 mW typical power consumption in the 48-LFCSP package.

Part Context

This component belongs to Analog Devices' family of clock and data recovery ICs optimized for optical communication interfaces. It integrates receiver functions such as quantization, signal level detect, and clock/data recovery into a single compact package, reducing the need for external components in fiber optic receiver designs.
