VSC8115 Description
VSC8115 Datasheet STS-12/STS-3 Multirate Clock and Data Recovery Unit .
The VSC8115 functions as a clock and data recovery (CDR) unit for SONET/SDH-based equipment to derive highspeed timing signals.
VSC8115 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
VSC8115 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
