Des — Clock Edge Select (RFB)
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 CLKOUT. If RFB is Low, data is strobed on the Falling edge of the CLKOUT. This allows for inter-
operability with downstream devices. The Des output does not need to use the same edge as the Ser input. This
feature may be controlled by the external pin or by register.
Des — Control Signal Filter — Optional
The deserializer provides an optional Control Signal (C3, C2, C1) filter that monitors the three control signals and
eliminates any pulses or glitches that are 1 or 2 parallel clock periods wide. Control signals must be 3 parallel
clock periods wide (in its HIGH or LOW state, regardless of which state is active). This is set by the CONFIG[1:0]
strap option or by I2C register control.
