Descriptions
Channel Input Source TI Filter Setting
These bits define the frequency divided ratio used to sample the TI signal. The
Digital filter in the SCTM is an N-event counter where N is defined as how many
valid transitions are necessary to output a filtered signal.
0000: No filter, the sampling clock is f
0001: f = f , N = 2
SAMPLING CLKIN
0010: f = f , N = 4
SAMPLING CLKIN
0011: f = f , N = 8
SAMPLING CLKIN
0100: f = f / 2, N = 6
SAMPLING DTS
0101: f = f / 2, N = 8
