ADN2807ACP-RL中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The ADN2807 provides the receiver functions of quantization, signal level detect, and clock and data recovery at rates of OC-3, OC-12, and 15/14 FEC. All SONET jitter requirements are met, including jitter transfer, jitter generation, and jitter tolerance. All specifications are quoted for –40°C to +85°C ambient temperature, unless otherwise noted.
