indirect by measuring the DAC1 (9 bit) output voltage for DAC1=0x200 or the DAC2 (8 bit)
output voltage for DAC2=0x100).
The PWR_STABLE functionality can be switched on/off. The default value is the switched off
mode.
Voltage sag detection electrical characteristics
Voltage regulator
The internal voltage regulator drives the external transistor for the 3.3V supply of the VCO
and PLL. The 3.3 V voltage regulator for the bus interface and the reference oscillator is fully
integrated.
Voltage regulator electrical characteristics
When an external 3.3 V supply is used for the VCO and PLL supply, special care has to be
taken on the supply voltages during the ramp-up phase:
●
●
The second prerequisite is automatically met using a 3.3 V Z-diode between the 5 V and the
3.3 V supplies.
the 3.3 V supply must never be higher than the 5 V supply;
the difference between 5 V and 3.3 V must never exceed 3.6 V.
