File Size : 116 KB Manufacturer:XILINX Description:The CD input may be driven by external circuitry that is moni- toring the incoming data stream. Optical modules have CD outputs that indicate the presence of light on the optical fiber and some copper based systems use external threshold de- tection circuitry to monitor the incoming data stream. The CD input is a 100K PECL compatible signal that should be held HIGH when the incoming data stream is valid. When CD is pulled to a PECL LOW (<2.5V Max.), the LFI output will tran- sition LOW and the Receiver PLL will align itself with the REFCLK8 frequency and the recovered data outputs (RSER) will remain LOW regardless of the signal level on the Receive data-stream inputs (RIN).
