ADN2814ACPZ

Overview

The ADN2814ACPZ is a clock and data recovery IC from Analog Devices, designed for continuous serial data rates ranging from 10 Mb/s to 675 Mb/s. It integrates a limiting amplifier, quantizer, and loss-of-signal detector within a single 3.3 V supply architecture. The device operates without an external reference clock, automatically locking to input data signals. Key electrical parameters include a typical power consumption of 435 mW at 132 mA, a differential input sensitivity of 3.3 mV p-p, and operation across a temperature range of -40°C to +85°C. It provides LVDS outputs for recovered clock and data.

Feature Summary

• Supports continuous data rates from 10 Mb/s to 675 Mb/s with automatic frequency acquisition.
• Exceeds SONET jitter requirements for transfer, generation, and tolerance.
• Features adjustable slice level (±95 mV) and independent loss-of-signal detection.
• Includes I²C interface for accessing optional features and status registers.

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 package variant against project requirements, as the ADN2814 series includes both tray (ACPZ) and reel (RL7) packaging options which may affect handling procedures. Confirm that the 32-LFCSP-WQ footprint matches the PCB design guidelines provided in the datasheet, particularly regarding the exposed pad connection to ground for thermal management.

Selection Notes

Select this component when designing fiber optic receivers requiring high integration and low power consumption. Ensure the application supports CML differential inputs and LVDS differential outputs. The device is suitable for environments where SONET/SDH jitter compliance is mandatory. Verify that the system can accommodate the 3.3 V single-supply requirement and the 5 mm × 5 mm package dimensions.

Part Context

The ADN2814 belongs to the ADN28xx family of timing and support products from Analog Devices. It serves as a receiver solution often paired with PIN diodes and TIA preamplifiers to form complete optical receiver modules. It is distinct from higher-speed variants like the ADN2812 derivative or the ADN2915 CDR, targeting lower bandwidth applications up to 675 Mb/s.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices for current alternatives if discontinuation occurs, noting that pin compatibility and electrical specifications must be verified before substitution.
