61.44 MHz. If on the other hand a lower frequency clcok is provided via CLK_DSP
input pin, the frequency of PDC (input or output) should not exceed the frequency
of DSP-clock-frequency / 4 (DSP clcok frequency devided by 4), in order to
guarantee a proper operation of the DELIC.
frequency. Usually this clock is generated internally by the internal PLL, in a
frequency of 61.44 MHz. In this case the values in the table above are valid. If a
lower frequency for DSP-clock is provided via CLK_DSP input pin, and PDC is
used as input, the low/high pulse width of PDC should not be smaller then
1.5 X DSP-clock-cycle (DSP-clock-cycle is the cycle time of the provided DSP
clock).
