VSC8115 - STS-12/STS-3 Multi Rate 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. The VSC8115 recovers the clock from the scrambled non-return to zero (NRZ) data operating at 622.08 Mbps (STS-12/OC-12/STM-4) or 155.52 Mbps (STS-3/OC-3/STM-1). After the c.

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
