ADN2818ACPZ-RL7

Overview

The ADN2818ACPZ-RL7 is a continuous rate clock and data recovery IC from Analog Devices, designed for serial data inputs ranging from 10 Mbps to 2.7 Gbps. It operates on a single 3 V to 3.6 V supply with a typical current consumption of 180 mA. The device features a proprietary dual-loop architecture that automatically locks to input data rates without an external reference clock. It provides differential CML recovered clock and data outputs in a 5 mm × 5 mm 32-lead LFCSP package.

Feature Summary

• Supports continuous data rates from 10 Mbps to 2.7 Gbps
• Exceeds ITU-T jitter specifications for SONET/SDH applications
• Integrated limiting amplifier with 200 mV p-p sensitivity
• Includes I²C interface for configuration and BER monitoring

Applications

• SONET OC-1, OC-3, OC-12, OC-48, and associated FEC rates
• Fibre Channel and Gigabit Ethernet (GbE)
• WDM transponders and regenerators/repeaters
• High-definition television (HDTV) signal processing

Procurement Notes

Verify the specific ADN2818 variant against the ADN2817, as the latter includes additional features like adjustable slice levels and lower power consumption. Confirm package integrity for the 32-LFCSP form factor. Ensure compatibility with the required output voltage standards (CML/LVCMOS/LVDS/LVPECL/LVTTL) supported by the device family.

Selection Notes

Select this component when automatic frequency acquisition without a reference clock is required. The ADN2818 is suitable for systems needing integrated limiting amplification. Consider the ADN2817 if higher sensitivity (5 mV p-p) or programmable LOS detection is necessary. Verify thermal management requirements given the 600 mW power dissipation in the compact LFCSP package.

Part Context

This part belongs to the ADN2817/ADN2818 series of clock and data recovery ICs. It shares the same core architecture and pinout with the ADN2817 but differs in input sensitivity and feature set. The ADN2818 is optimized for applications where moderate input sensitivity is sufficient, offering a balance between performance and power consumption.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The ADN2817 is a related variant within the same family but has distinct electrical characteristics regarding sensitivity and control features.
