The oversampling module described in this application note performs 3/4/5/6X oversampling. The oversampling ratio is selectable during operation to facilitate multi-rate applications. It is designed to accept 20 bits of oversampled data and to output 10 bits of extracted data to the user interface. This module can be used with the Virtex-II Pro™ RocketIO™ Multi-Gigabit Transceiver (MGT) to achieve line rates of 200 Mb/s to 1000 Mb/s.
