CE_CLK (Convolution Encoder Clock)
The CE_CLK input drives the timing of the convolution
encoder. Data is read in on CE_IN on the rising edge of
CE_CLK and output on CE_OUT on both the rising and falling
edge of CE_CLK.
Note: The output data rate is twice the input data rate.
A 50% duty cycle clock is required. If this is provided by the
CLKS output, data can be read directly from RSE_OUT to the
CE_IN input (see figure 3).
CE_OUT (Convolution Encoder Output)
This signal carries the output data from the convolution
encoder. The data rate on CE_OUT is twice that of CE_IN.
CLK_OUT (Clock Out)
CLK_OUT is a buffered output of the CLK input signal. If
CLKS is connected to CE_CLK to drive the convolution
encoder, CE_OUT can be captured on the falling edge of
CLK_OUT.
