ADN2815ACPZ-500RL7

Overview

The ADN2815ACPZ-500RL7 is a continuous rate clock and data recovery (CDR) integrated circuit manufactured by Analog Devices Inc. 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 recovered clock and data signals. 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
• Integrated I2C interface for accessing optional features and status registers
• Loss-of-lock indicator with normal, reference clock, and static modes

Applications

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

Procurement Notes

Verify the specific ordering suffix -500RL7 against the manufacturer's current datasheet to confirm packaging details such as reel size and tape specifications. Confirm availability status through authorized distributors as supply conditions may vary. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitivity of the CMOS components.

Selection Notes

Select this component when designing receivers for SONET/SDH or Fibre Channel applications requiring jitter performance exceeding standard Telcordia GR-253-CORE limits. The absence of a required external reference clock simplifies board layout compared to traditional PLL-based CDRs. Ensure the PCB design accommodates the 32-LFCSP-WQ package dimensions and provides adequate thermal dissipation via the exposed paddle ground connection.

Part Context

The ADN2815 belongs to Analog Devices' specialized clock and timing product line focused on high-speed serial communication receivers. It serves as a core component for signal regeneration in optical networking equipment. The device integrates quantization, clock recovery, and data retiming functions into a single chip, reducing the bill of materials for transceiver designs operating at speeds up to 1.25 Gb/s.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices for current alternative recommendations based on specific pinout and electrical compatibility requirements.
