8.1.3 Operating Characteristics
For the following conditions unless otherwise specified:
V_DD = AV_DD = DV_DD = 3.3V; V_DDIO = 1.6V to V_DD; V_SS = AV_SS = DV_SS. LO Level = -15dBm and
T_AMB = -40ºC to +85ºC.

Notes:
0. Powersave mode includes the case after general reset with all analogue and digital supplies
applied and also the case with V_DD applied but with all analogue supplies disconnected (i.e. in
this latter scenario power from V_DD will not exceed the specified value, whatever the state of the
registers). At T_AMB = 25ºC, not including any current drawn from device pins by external
circuitry.
1. For CMX993 only. Add 1mA for CMX993W device. T_AMB = 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.
