R
Differential Clock Input And Output With SMA Connectors (31)
High-precision clock signals can be input to the FPGA using differential clock signals
brought in through 50
Ω
SMA connectors, thereby allowing an external function generator
or other clock source to drive the differential clock inputs that directly feed the global clock
input pins of the FPGA. The FPGA can be configured to present a 100
Ω
termination
impedance.
