ADN2816ACPZ-RL7

Overview

The ADN2816ACPZ-RL7 is a continuous-rate clock and data recovery (CDR) integrated circuit manufactured by Analog Devices Inc. It provides quantization and CDR functions for serial data inputs ranging from 10 Mb/s to 675 Mb/s. The device automatically locks to any data rate within this range without requiring an external reference clock or programming. Key electrical specifications include a single 3.3 V supply operation with typical power dissipation of 366 mW, an operating temperature range of -40°C to +85°C, and a maximum supply voltage of 3.6 V. It features a patented delay- and phase-locked loop architecture that exceeds SONET jitter requirements.

Feature Summary

• Continuous rate operation from 10 Mb/s to 675 Mb/s with automatic locking capability
• Exceeds SONET OC-1/OC-3/OC-12 jitter transfer, generation, and tolerance requirements
• Patented D/PLL architecture eliminates jitter peaking for signal regenerator applications
• Single-supply 3.3 V operation with typical power consumption of 366 mW

Applications

• SONET OC-1, OC-3, and OC-12 systems including associated FEC rates
• Fibre Channel, ESCON, Fast Ethernet, and SDI interfaces
• WDM transponders and optical regenerators/repeaters
• Broadband crossconnects and routers
• High-speed test equipment

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the required reel packaging configuration before procurement. Confirm that the LFCSP-32 package variant matches the PCB footprint design. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS input structures. Cross-reference the Rev. C datasheet specifications against current manufacturing revisions to ensure parameter consistency.

Selection Notes

Select the ADN2816ACPZ-RL7 when designing receivers for SONET/SDH or Fibre Channel links requiring continuous rate adaptation up to 675 Mb/s. This component is suitable for applications needing low jitter peaking in cascaded regenerator topologies. Verify that the system can accommodate the 3.3 V single-supply requirement and the thermal characteristics of the 32-lead LFCSP package. Consider the optional I2C interface if dynamic register configuration is required for advanced monitoring.

Part Context

The ADN2816 belongs to Analog Devices' family of high-speed clock and data recovery ICs designed for telecommunications and data communication standards. It serves as a receiver solution for serial data streams where jitter performance and automatic frequency acquisition are critical. The device integrates the limiting amplifier, phase detector, VCO, and output buffers into a compact 5 mm × 5 mm package, simplifying board layout for high-density designs.
