11.31.2
When the Carrier Clock output is selected, the LFDATA
output is a square pulse of the input carrier clock and
available as soon as the AGC stabilization time (T
completed. There are two Configuration register options
for the carrier clock output: (a) clock divide-by one or (b)
clock divide-by four, depending on bit DATOUT<7> of
Configuration Register 2 (Register 11-3). The carrier
clock output is available immediately after the AGC
settling time. The Output Enable Filter, AGCSIG, and
MODMIN options are applicable for the carrier clock
output in the same way as the demodulated output. The
input channel can be individually enabled or disabled for
the output. If more than one channel is enabled, the
output is the sum of each output of all enabled channels.
Therefore, the carrier clock output waveform is not as
precise as when only one channel is enabled. It is
recommended to enable one channel only if a precise
output waveform is desired.
There will be no valid output if all three channels are
disabled. See Figure 11-13 for carrier clock output
examples.
