Future Readiness: The RCG Will need to be capable of driving a DAC at 2^17 Hz (131072 Hz)
LIGO custom built 32-bit DACs (E2200440) are slated for use in O5. As a part of their use, we want to explore driving the test inputs to the OMC DCPD sensing chain (e.g. like those in LHO:62653 and LHO:67760) at as high a sampling frequency as 2^17 Hz (131072 Hz, some might colloquially refer to this as "128 kHz"), but at least at the native rate of the current IO chassis (2^16 Hz = 65536 Hz).
@erik.vonreis suggests that prepping the RCG for such a drive may not be that hard, but it needs some eyeballs on it at least.
FYI: This is NOT a priority before O4 starts. However, I might imagine @daniel.sigg and @marc.pirello might want this RCG change to support their prototyping efforts on test stands.
