ADN2819ACPZ-CML

Overview

The ADN2819ACPZ-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 rates. The device features CML differential inputs and outputs, a single-supply voltage range of 3V to 3.6V, and typical power consumption of 540 mW. It meets SONET jitter requirements and includes a loss-of-signal detector. The component is housed in a 48-lead LFCSP (7x7 mm) package.

Feature Summary

• Multirate operation from OC-3 (155.52 Mbps) to OC-48 (2.488 Gbps) and Gigabit Ethernet
• Integrated limiting amplifier with adjustable slice level and loss-of-signal detection
• Supports native rates and 15/14 FEC digital wrappers without reference clock changes
• Flexible reference clock options including on-chip oscillator or external LVPECL/LVDS/LVCMOS/LVTTL inputs

Applications

• SONET OC-3/-12/-48 and SDH STM-1/-4/-16 systems
• WDM transponders and regenerators/repeaters
• Test equipment and backplane applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and feature set. Confirm availability status as supply conditions may vary by region. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this component for high-speed optical receiver designs requiring integrated clock recovery and signal conditioning. Consider the 48-lead LFCSP package size for space-constrained PCB layouts. Verify that the system reference clock frequency matches one of the supported options: 19.44 MHz, 38.88 MHz, 77.76 MHz, or 155.52 MHz.
