Stratix devices support systems based on single data rate (SDR)
operations applications by allowing you to directly transmit out the

interfaces, and support various data rates.
An additional differential channel is automatically configured to produce
the transmitter clock output signal and is transmitted along with the data.
For example, when a system is required to transmit 10 Gbps with a 1-to-
1 clock-to-data ratio, program the SERDES with sixteen high-speed
channels running at 624 Mbps each. The Quartus II software
