ICS1887M中文资料ICST数据手册PDF规格书

General Description

The ICS1887 is designed to provide high performance clock recovery and generation for 125 MHz serial data streams. The ICS1887 is ideally suited for LAN transceiver applications in either FDDI or Fast Ethernet environments. The ICS1887 converts NRZ to/from NRZI data in addition to providing a 5-bit parallel digital data transmit and receive interface.
