ADN2815ACPZ-RL7

Overview

The ADN2815ACPZ-RL7 is a continuous-rate clock and data recovery (CDR) integrated circuit designed for SONET/SDH applications. It supports serial data input rates from 10 Mb/s to 1.25 Gb/s without requiring an external reference clock or programming. The device features a patented delay- and phase-locked loop architecture that automatically locks to input data frequencies. It accepts CML differential inputs and provides LVDS differential outputs for both recovered clock and retimed data. Operating on a single 3.3 V supply, it typically consumes 390 mW of power. The component is housed in a compact 5 mm × 5 mm 32-lead LFCSP package with an exposed pad.

Feature Summary

• Continuous rate operation from 10 Mb/s to 1.25 Gb/s with automatic frequency acquisition
• Exceeds SONET jitter transfer, generation, and tolerance requirements
• Patented DPLL architecture minimizes jitter peaking for signal regeneration
• I2C interface for optional feature access and register configuration

Applications

• SONET OC-1, OC-3, OC-12, and associated FEC rates
• Fibre Channel and Gigabit Ethernet (GbE)
• WDM transponders and regenerators/repeaters
• Broadband crossconnects and routers

Procurement Notes

Verify the specific suffix RL7 against the manufacturer's current ordering guide to confirm packaging details such as reel quantity. Confirm RoHS compliance status through official documentation prior to procurement. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS components.

Selection Notes

Select this component when designing receivers for SONET/SDH standards up to OC-12 or equivalent data rates. The absence of a required external reference clock simplifies board design compared to other CDRs. Ensure the PCB layout accommodates the 32-LFCSP package dimensions and provides adequate thermal grounding via the exposed pad.

Part Context

This part belongs to the ADN2815 series of clock and data recovery ICs manufactured by Analog Devices Inc. It is specifically engineered for optical communication interfaces requiring robust jitter performance. The device integrates limiting amplification, quantization, and retiming functions into a single chip.

Replacement Considerations

Check the ADN2815ACPZ for tray-packaged equivalents. For higher speed requirements, consider the ADN2812 or ADN2817 models which support rates up to 2.7 Gb/s. Verify pin compatibility if substituting within the ADN28xx family.
