Overview
The ADN2813ACPZ-500RL7, produced by Analog Devices Inc., is a highly integrated clock and data recovery (CDR) IC designed for continuous data rates ranging from 12.3 Mb/s to 1.25 Gb/s. This device is particularly suited for fiber optic receiver applications, offering automatic locking to all data rates without the need for an external reference clock or programming. It meets all SONET jitter requirements, including jitter transfer, jitter generation, and jitter tolerance. The ADN2813 can be used in conjunction with a PIN diode and a TIA preamplifier to implement a low-cost, low-power fiber optic receiver.
