Figure 5. Timing for clock, serial in, serial out, latch enable and outputs

The correct sampling of the data depends on the stability of the data at SDI on the rising

edge of the clock signal and it is assured by a proper data setup and hold time (tSU(D) and

th(D)), as shown in Figure 5. The same figure shows the propagation delay from CLK to SDO

(tPLH/tPHL). Figure 5 describes also the minimum duration of CLK, LE pulses (tW(CLK)) and

tW(L) respectively and the propagation delay from LE to OUTn (tPLHLE and tPHLLE) in the

hypothesis that all channels have already been enabled by PWM counter.
