PRODUCTION DATA.
The RFB pin determines the edge that the data is strobed on. If RFB is High, output data is strobed on the Rising edge of the PCLK. If RFB is Low, data is strobed on the Falling edge of the PCLK. This allows for inter-operability with downstream devices. The deserializer output does not need to use the same edge as the serializer input. This feature may be controlled by the external pin or by register.
