Asserting SRC_STOP# causes all DIF outputs to stop after their next transition (if the control register settings allow the output
to stop). When the SRC_STOP# drive bit is ‘0’, the final state of all stopped DIF outputs is DIF = High and DIF# = Low. There
is no change in output drive current. DIF is driven with 6xIREF. DIF# is not driven, but pulled low by the termination. When the
SRC_STOP# drive bit is ‘1’, the final state of all DIF output pins is Low. Both DIF and DIF# are not driven.
SRC_STOP# - Assertion
All stopped differential outputs resume normal operation in a glitch-free manner. The de-assertion latency to active outputs is
2-6 DIF clock periods, with all DIF outputs resuming simultaneously. If the SRC_STOP# drive control bit is ‘1’ (tri-state), all
stopped DIF outputs must be driven High (>200 mV) within 10 ns of de-assertion.
SRC_STOP# - De-assertion (transition from '0' to '1')
The SRC_STOP# signal is an active-low asynchronous input that cleanly stops and starts the DIF outputs. A valid clock must
be present on SRC_IN for this input to work properly. The SRC_STOP# signal is de-bounced and must remain stable for two
consecutive rising edges of DIF# to be recognized as a valid assertion or de-assertion.
