Clock Timing
Parallel and Parallel Interleaved Port Configuration Clock Rates
Parallel and parallel interleaved port configurations have other limiting factors for the clock and
sample rates:
— logic type
— Clocks per sample selection
— IQ or IF digital signal type
Clocks per sample (clocks/sample) is the ratio of the clock to sample rate. For an IQ signal type, the
sample rate is reduced by the clocks per sample value when the value is greater than one. For an IF
signal or an input signal, clocks per sample is always set to one. Refer to Table 10-5 for the Output
mode parallel and parallel interleaved port configuration clock rates.
For Input mode, the maximum clock rate is limited by the following factors:
— sample size
— data type
Refer to
Table 10-6 for the Input mode parallel and parallel interleaved port configuration clock
rates.
Clock Source
The clock signal for the N5102A module is provided in one of three ways through the following
selections:
Table 10-5 Output Parallel and Parallel Interleaved Clock Rates
Logic Type Signal Type Minimum Rate Maximum Rate
LVDS IQ 1 x (clocks/sample) kHz the smaller of: 100 x (clocks /sample) MHz
or
400 MHz
IF 4 kHz 400 MHz
Other IQ 1 x (clocks/sample) kHz the smaller of: 100 x (clocks /sample) MHz
or
150 MHz
IF 4 kHz 150 MHz
Table 10-6 Input Parallel and Parallel Interleaved Clock Rates
Logic Type Data Type Minimum Rate Maximum Rate
N/A Samples 1 kHz 200 MHz
Pre-FIR Samples 1 kHz 100 MHz
