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
applications 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
of 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.
Features
Data and clock recovery for: 32.064 Mb/s (Japan)
34.368 Mb/s (Europe - E3) 125 MHz (Ethernet)
139.264 Mb/s (Europe - E4)
Clock multiplication from either a crystal, differential
or single-ended timing source
Continuous clock in the absence of data
No external PLL components
Lock/Loss status indicator output
Loopback mode for system diagnostics
Selectable loop timing mode
PECL drivers with settable sink current
The ICS1886 utilizes advanced CMOS phase-locked loop
technology which combines high performance and low
Pin Configuration
power at a greatly reduced cost.
