MUTE signal active low
When low, the IG signal on the CDCLVC1102 forces the outputs to low.
The MUTE signal on the TDC mezzanine is directly connected to the IG
pin, therefore when MUTE = '1', the outputs are active and when MUTE
='0' the outputs are grounded.
The name of the MUTE_INPUTS signal should be change to ENABLE_INPUTS to be consistent.
