ADN2815ACPZ

Overview

The ADN2815ACPZ 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 operates on a single 3.3 V supply, with a voltage range of 3.0 V to 3.6 V, and consumes approximately 131 mA at maximum speed. The unit is housed in a 32-lead LFCSP-WQ package measuring 5 mm × 5 mm.

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
• No external reference clock required for standard lock-to-data mode
• I2C interface for accessing optional features and configuration registers

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 against the manufacturer's current datasheet to confirm packaging type, as suffixes may indicate tray versus reel configurations. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the supplier provides valid traceability documentation for the Analog Devices Inc. component.

Selection Notes

Select this component for applications requiring a single-channel CDR with no external reference clock dependency. The device accepts CML differential inputs and provides LVDS differential outputs. Ensure the design accommodates the 3.3 V single-supply requirement and the thermal dissipation characteristics of the 32-LFCSP package. Verify that the I2C bus timing meets the system controller specifications.

Part Context

The ADN2815 belongs to the ADN28 series of clock and data recovery ICs designed for high-speed optical communication interfaces. It serves as a receiver function block providing quantization and retiming for NRZ encoded data streams. The device integrates a voltage-controlled oscillator, phase detector, and loop filters within a compact surface-mount footprint suitable for dense PCB layouts.
