ADN2917ACPZ-RL7

Overview

The ADN2917ACPZ-RL7 is a continuous rate clock and data recovery IC from Analog Devices, supporting serial data inputs from 8.5 Gbps to 11.3 Gbps. It integrates a limiting amplifier and equalizer, eliminating the need for an external reference clock or programming to lock onto data signals. The device exceeds SONET/SDH jitter specifications for transfer, generation, and tolerance. Key electrical parameters include a quantizer sensitivity of 9.2 mV p-p in limiting amplifier mode and power dissipation ranging from 352 mW at 8.5 Gbps to 430 mW at 11.3 Gbps in equalizer mode without clock output. It operates on 1.2 V, 1.8 V to 3.3 V, and 3.3 V supplies within a -40°C to +85°C temperature range.

Feature Summary

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the LFCSP-24 is sensitive to moisture. Check datasheet revisions for any updates to pin configurations or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component for high-speed optical networking requiring robust jitter performance without external reference clocks. Ensure input signal levels match the specified sensitivity thresholds for either limiting amplifier or equalizer modes. Verify that the system power supply rails align with the required 1.2 V, 1.8 V–3.3 V, and 3.3 V specifications.

Part Context

This part belongs to the ADN2917 series of clock and data recovery ICs designed for high-speed serial communication. It is functionally similar to other devices in the ADN29xx family but optimized for the 8.5 Gbps to 11.3 Gbps range. The ACPZ-RL7 suffix indicates the specific lead-free tape and reel packaging configuration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative CDRs based on compatible data rates, package dimensions, and jitter performance metrics if replacement is necessary.

FAQ

Does the ADN2917 require an external reference clock?

No, the ADN2917 automatically locks to data signals without the need for an external reference clock or additional programming.

What is the typical quantizer sensitivity in limiting amplifier mode?

The typical quantizer sensitivity is 9.2 mV p-p when operating in limiting amplifier mode.

How is the Loss of Signal (LOS) threshold configured?

The LOS threshold is programmable via the I2C interface, allowing users to set the detection level between 5 mV p-p and 128 mV p-p.
