Notes:
0. Powersave mode includes the case after general reset with all analogue and digital supplies
applied and also the case with VDD applied but with all analogue supplies disconnected (i.e. in
this latter scenario power from VDD will not exceed the specified value, whatever the state of the
registers). At T

1. For CMX993 only. Add 1mA for CMX993W device. T
= 25ºC only.

2. Assumes 30pF on each C-BUS interface line and an operating serial clock frequency of 5MHz.
3. Time from the rising edge of the last serial clock input following CSN being asserted for a write
to the appropriate control register.
