Overview
The ADN2812ACPZ from Analog Devices Inc. is a Continuous Rate Clock and Data Recovery IC with an Integrated Limiting Amplifier. This device is designed to operate over a wide range of data rates, from 12.3 Mb/s to 2.7 Gb/s, making it suitable for various high-speed data transmission applications. It can be used in conjunction with a PIN diode and a TIA preamplifier to implement a highly integrated, low-cost, and low-power fiber optic receiver. The ADN2812 automatically locks to all data rates without the need for an external reference clock or programming, and it meets all SONET jitter requirements, including jitter transfer, jitter generation, and jitter tolerance.
