These specifications are for a three-resistor RSDS implementation. For single-resistor RSDS in ×10 through ×2
modes, the maximum data rate is 170 Mbps and the corresponding maximum input clock frequency is 85 MHz.
For single-resistor RSDS in ×1 mode, the maximum data rate is 170 Mbps, and the maximum input clock frequency
is 170 MHz. For more information about the different RSDS implementations, refer to the

In order to determine the transmitter timing requirements, RSDS receiver
timing requirements on the other end of the link must be taken into
consideration. RSDS receiver timing parameters are typically defined as
