ADN2814ACPZ-500RL7

Overview

The ADN2814ACPZ-500RL7 is a clock and data recovery (CDR) integrated circuit from Analog Devices, designed for continuous data rates ranging from 10 Mb/s to 675 Mb/s. It operates on a single 3.3 V supply with typical power consumption of 435 mW. The device features an integrated limiting amplifier and quantizer, accepting CML differential inputs. It provides LVDS differential outputs for recovered clock and data signals. Key specifications include a typical quantizer sensitivity of 3.3 mV p-p, adjustable slice levels, and loss-of-signal detection. The component is housed in a 32-lead LFCSP package.

Feature Summary

• Integrated Clock and Data Recovery (CDR) supporting 10 Mb/s to 675 Mb/s data rates
• Exceeds SONET jitter transfer, generation, and tolerance requirements
• Low quantizer sensitivity of 3.3 mV typical at BER = 1 × 10⁻¹⁰
• Adjustable Loss-of-Signal (LOS) detector range from 2.3 mV to 19 mV
• I²C interface for accessing optional features and configuration

Applications

• SONET OC-1, OC-3, and OC-12 systems including FEC rates
• ESCON and Fast Ethernet interfaces
• Serial digital video interfaces (DTV)
• WDM transponders and regenerators/repeaters
• Broadband cross-connects and routers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging details such as reel size or tape width. Confirm that the 32-LFCSP package variant matches the required PCB footprint dimensions. Ensure compatibility with the 3.3 V single-supply requirement and check for any recent product change notices regarding thermal characteristics or pinout revisions.

Selection Notes

Select this component when a self-contained CDR solution is needed without an external reference clock. It is suitable for applications requiring high jitter tolerance and low power consumption in a compact package. Consider the I²C interface if dynamic configuration of LOS thresholds or output boost is required. Verify that the input signal amplitude falls within the quantizer's operating range for optimal performance.

Part Context

This part belongs to the ADN2814 series of clock and data recovery ICs. It is functionally compatible with other ADN28xx family members but offers specific integration of the limiting amplifier and quantizer. The device is designed to replace discrete CDR solutions, reducing board space and component count in fiber optic receiver designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices for direct replacements or pin-compatible alternatives within the ADN28xx series.
