Data Rate Reconfiguration Mode Using RX Local Divider
The RX local divider resides in the RX PMA block for every channels. This is a
hardware feature where a /2 divider is available in each of the receiver channel for the
supported device. You can use this RX local divider to reconfigure the data rate at the
receiver channel. This can be used for protocols such as SDI that has data rates in
divisions of 2.
By using this RX local divider, you can support two different data rates without using
additional transceiver PLLs. This dynamic reconfiguration mode is available only for
the receiver and not applicable to the transmitter. This reconfiguration mode using the
RX local divider (/2) is only supported and available in EP4CGX30 (F484 package),
EP4CGX50, and EP4CGX75 devices.
For more information about this RX local divider, refer to the
