ADN2817ACPZ

Overview

The ADN2817ACPZ is a continuous-rate clock and data recovery (CDR) integrated circuit manufactured by Analog Devices Inc. It supports serial data input rates from 10 Mbps to 2.7 Gbps without requiring an external reference clock or programming. The device features a proprietary dual-loop architecture, an integrated limiting amplifier with 5 mV p-p sensitivity, and adjustable slice levels. It operates on a single 3.3 V supply (3.0 V to 3.6 V range), consuming 650 mW of power. The component is housed in a compact 5 mm × 5 mm 32-lead LFCSP package and functions within an ambient temperature range of −40°C to +85°C.

Feature Summary

• Continuous rate operation from 10 Mbps to 2.7 Gbps with automatic locking
• Integrated limiting amplifier providing 5 mV p-p differential input sensitivity
• Proprietary dual-loop clock recovery architecture exceeding ITU-T jitter specifications
• Built-in PRBS generator/detector and BER monitor for signal integrity verification

Applications

• SONET OC-1, OC-3, OC-12, OC-48, and associated FEC rates
• Fibre Channel, 2× Fibre Channel, GbE, and HDTV systems
• WDM transponders and regenerators/repeaters
• High-speed test equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision. Packaging variations such as tape-and-reel versus tray may exist for different part numbers within the same family. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure compliance with RoHS directives and moisture sensitivity level requirements during storage and handling.

Selection Notes

Select the ADN2817ACPZ when high sensitivity (5 mV p-p) and adjustable slice levels are required, distinguishing it from the ADN2818 variant which lacks these features. Ensure the design accommodates the 3.3 V single-supply requirement and the 650 mW power dissipation. Verify that the 32-LFCSP package footprint matches the PCB layout guidelines provided in the datasheet, particularly regarding the exposed paddle connection to VEE.

Part Context

The ADN2817ACPZ belongs to the ADN2817/ADN2818 series of clock and data recovery ICs designed for high-speed optical and electrical interfaces. It serves as a receiver function block for quantization, signal level detection, and clock/data recovery. The device is often paired with PIN diodes and TIA preamplifiers to form complete fiber optic receiver solutions. It shares the same package and core architecture with the ADN2818, differing primarily in input stage capabilities.

Replacement Considerations

The ADN2818ACPZ is a pin-compatible alternative within the same series but lacks the integrated limiting amplifier and adjustable slice level features. It offers lower power consumption (600 mW) but requires higher input signal levels (200 mV p-p). No other direct cross-model replacements are documented in the provided source material.
