Description: STS-12/STS-3 Multi Rate Clock and Data Recovery Unit

Features

* Performs clock and data recovery for 622.08 Mbps (STS-12/OC-12/STM-4) or 155.52 Mbps (STS-3/OC-3/STM-1) NRZ data
* 19.44 MHz reference frequency LVTTL input
* Lock Detect output pin monitors data run length and frequency drift from reference clock
* Data is retimed at the output

Applications

* when it is required to hold the CLKOUT± output to within ±500 ppm of the reference clock and to force the DATAOUT± output to the logic LOW state. Reference Clock Upon powering up the VSC8115, it is recommended that the reference clock be present at least 40 bit times before the data signal is introd
