Figure 74. LM97593 output circuit
The channel outputs are accessible through serial output pins and a 16-bit parallel output port. The RDY pin is
provided to notify the user that a new output sample period (OSP) has begun. OSP refers to the interval between
output samples at the decimated output rate. For example, if the input rate (and clock rate) is 52 MHz and the
overall decimation factor is 192 (N=48, F2 decimation=2) the OSP will be 3.69 microseconds which corresponds
to an output sample rate of 270.833kHz. An OSP starts when a sample is ready and stops when the next one is
ready.
