ADN2812ACPZ-RL

Overview

The ADN2812ACPZ-RL is a continuous-rate clock and data recovery (CDR) integrated circuit manufactured by Analog Devices Inc. It supports serial data input rates from 12.3 Mb/s to 2.7 Gb/s without requiring an external reference clock or programming. The device features an integrated limiting amplifier, quantizer, and loss of signal detector. It operates on a single 3.0 V to 3.6 V supply with a typical power consumption of 750 mW. The component meets SONET jitter requirements for transfer, generation, and tolerance. It is housed in a 5 mm × 5 mm 32-lead LFCSP package.

Feature Summary

• Continuous rate operation from 12.3 Mb/s to 2.7 Gb/s
• Exceeds SONET GR-253-CORE jitter specifications
• Integrated limiting amplifier with adjustable slice level
• Loss of signal (LOS) detect range: 3 mV to 15 mV
• I2C interface for optional feature access

Applications

• SONET OC-1/OC-3/OC-12/OC-48 and associated FEC rates
• Fibre Channel, 2x Fibre Channel, GbE, HDTV
• WDM transponders
• Regenerators/repeaters
• Test equipment
• Broadband cross-connects and routers

Procurement Notes

Verify the specific ordering suffix RL against the manufacturer's current documentation to confirm reel packaging details. Confirm availability status as distribution channels may list restricted supply conditions. Ensure the 32-LFCSP-WQ package dimensions match the target PCB footprint. Validate that the operating temperature range of -40°C to +85°C aligns with system requirements.

Selection Notes

Select this component for applications requiring automatic lock to data rates between 12.3 Mb/s and 2.7 Gb/s without external reference clocks. Ensure the design accommodates the 750 mW typical power dissipation and provides adequate thermal management for the exposed pad. Verify compatibility with CML input/output signaling levels. Consider the I2C interface if dynamic configuration of LOS thresholds or squelch modes is required.

Part Context

The ADN2812 belongs to the ADN2812 series of clock and data recovery ICs. It is designed to replace discrete receiver solutions by integrating quantization, signal level detection, and CDR functions. The device is suitable for fiber optic receivers when paired with a PIN diode and TIA preamplifier. It serves as a key component in high-speed optical communication systems requiring strict jitter performance.
