Parameters

Timestamp frequency scaling
— Frequency scaling for the ADC frequency
/4
(default) |
/8
|
/16
|
/32
Specify the division factor for the clock frequency used in the ADC.
Dependencies
To enable this parameter, select the Enable timestamp output parameter in the CDSP block in the Simulink model.
Gate source to trigger timestamp

Specify the source of the gate signal to trigger the timestamp.
Note
You must configure the appropriate trigger from the PWM block with a rate
(1/initial clock frequency of PWM) that is greater than the conversion time
of the filtered data output. Calculate this conversion time as |Size of
filtered data x clock cycles / FADC|. For the filter
chain FC0
with analog to digital conversion
frequency (FADC) of 160 MHz, 128 filter taps, and a
decimation rate of 1, it requires 249 clock cycles to output correct
filtered data.
