ICS1886
FDDI / Fast Ethernet PHYceiverTM
General Description
The ICS1886 is designed to provide high performance clock recovery and generation for either 32.064 Mb/s, 34.368 Mb/s, 125 Mb/s or 139.264 Mb/s NRZ or NRZI serial data streams. The ICS1886 is ideally suited for LAN transceiver applications in either European or Japanese communication environments. The ICS1886 also operates at the 100Mbit Ethernet frequency of 125 MHz. This is ideal for serial Ethernet data a p p l i c a t i o n s where no serial to parallel conversion is required. Clock and data recovery is performed on an input serial data stream or the buffered transmit data depending upon the state o f the loopback input. A continuous clock source will continue to be present even in the absence of input data. All internal timing is derived from either a low cost crystal or an external clock module. The ICS1886 utilizes advanced CMOS phase-locked loop t e c h n o l o g y which combines high performance and low power at a greatly reduced cost.
