Total power dissipation
Total power dissipation needs to be less
than 1W to keep junction temperature in
specified range
I_Pd
Power-down current consumption
XPD=LOW, temp=27ºC;
No activity on I²C
I_Sb
Stand-by current consumption XPD=HIGH, pulse generation is stopped
I_Nom
Operating current consumption
Without output switching current
XPD=HIGH, temp=27ºC, VCO powered
I_Idle
Idle mode current consumption down, no digital activity; mode set by I²C,
frequency trimming preserved
