ADN2913ACPZ-RL7

Overview

The ADN2913ACPZ-RL7 is a continuous-rate clock and data recovery IC from Analog Devices, designed for serial data inputs ranging from 6.5 Mbps to 8.5 Gbps. It operates without an external reference clock in standard mode, automatically locking to input data rates. The device features integrated limiting amplifier and equalizer options, with quantizer sensitivity of 6.3 mV typical in limiting amplifier mode. Power supplies include VCC at 1.14 V to 1.26 V, VDD at 2.97 V to 3.63 V, and VCC1 at 1.62 V to 3.63 V. It is housed in a 24-lead LFCSP package.

Feature Summary

• Supports continuous data rates from 6.5 Mbps to 8.5 Gbps without requiring an external reference clock.
• Exceeds SONET/SDH jitter transfer, generation, and tolerance specifications.
• Includes programmable jitter transfer bandwidth to support G.8251 OTN standards.
• Features I2C interface for configuration, LOS threshold programming, and PRBS generation/detection.

Applications

• SONET/SDH OC-1, OC-3, OC-12, OC-48, and associated FEC rates
• 1GE, 1GFC, 2GFC, 4GFC, 8GFC, and CPRI OS/L.6 up to OS/L.60
• Rate regenerators and repeaters

Procurement Notes

Verify the specific ordering suffix RL7 against official documentation to confirm reel packaging details. Confirm current availability status as product lifecycle information may indicate end-of-life or limited supply conditions. Ensure compliance with humidity sensitivity levels and soldering guidelines for the LFCSP package during procurement planning.

Selection Notes

Select this component for applications requiring CDR functionality up to 8.5 Gbps where no external reference clock is available. Consider power dissipation requirements, which range from 340 mW to 446.6 mW depending on mode and data rate. Verify that the 24-LFCSP package size fits the design constraints and that thermal management meets the specified junction-to-ambient resistance.

FAQ

Does the ADN2913 require an external reference clock?

No, the ADN2913 automatically locks to all data rates without the need for an external reference clock or programming in its standard Lock to Data (LTD) mode.

What is the typical quantizer sensitivity of the ADN2913?

The typical quantizer sensitivity is 6.3 mV p-p when operating in limiting amplifier mode.

How does the ADN2913 handle Loss of Signal (LOS)?

The receiver front-end includes an LOS detector circuit that indicates when the input signal level falls below a user-programmable threshold via I2C. The circuit has hysteresis to prevent chatter at the LOS output.
