Notes to Figure 3–11 :
(1) This frequency can be either 74.175 or 74.25 MHz, to support 1.4835 or 1.485 Gbps HD-SDI respectively.
(2) The multiplexer must not be in the device.
(3) This frequency can be either 148.35 or 148.5 MHz, to support 2.967 or 2.970 Gbps HD-SDI respectively.
(4) You can source both 148.5 MHz and 148.35 MHz together if the additional clock port is enabled.
