ADN2816ACPZ

Overview

The ADN2816ACPZ is a continuous-rate clock and data recovery (CDR) integrated circuit manufactured by Analog Devices Inc. It provides receiver functions including quantization and data retiming for serial data rates ranging from 10 Mb/s to 675 Mb/s. The device automatically locks to input data without requiring an external reference clock or programming. Key electrical parameters include a single 3.3 V supply operation, typical power consumption of 366 mW, and an operating temperature range of −40°C to +85°C. It features CML differential inputs and LVDS differential outputs in a 32-lead LFCSP package.

Feature Summary

• Continuous rate operation supporting data speeds from 10 Mb/s to 675 Mb/s
• Patented delay- and phase-locked loop architecture with no reference clock required
• Exceeds SONET jitter transfer, generation, and tolerance requirements
• Integrated I2C interface for accessing optional features and status registers

Applications

• SONET OC-1, OC-3, and OC-12 systems with associated FEC rates
• Fibre Channel, ESCON, Fast Ethernet, and SDI interfaces
• WDM transponders and signal regenerators/repeaters
• Broadband crossconnects and routers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging type and lead time. Confirm that the component meets RoHS compliance standards as indicated in the datasheet. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitivity of the CMOS technology.

Selection Notes

Select this component when designing receivers for SONET/SDH or Fibre Channel applications requiring automatic rate adaptation between 10 Mb/s and 675 Mb/s. The device is suitable for environments needing low jitter peaking and high jitter tolerance. Consider the 32-LFCSP package dimensions and thermal characteristics if space or heat dissipation is a constraint in the PCB layout.

Part Context

The ADN2816 belongs to Analog Devices' family of clock and data recovery ICs designed for high-speed serial communication. It serves as a specialized timing solution for optical and copper-based digital links. The device integrates a limiting amplifier, phase detector, voltage-controlled oscillator, and output buffers into a single compact package.
