Power-on reset
The power-on detection threshold voltage VPOR is set to
VCC = 2 V at room temperature. Below this threshold, the
device is reset to the power-on state.
At power-on state, the charge pump current is set to
280
A, the tuning voltage output is disabled, the test
bits T2, T1 and T0 are set to logic 001 (automatic charge
pump switch ‘ON’) and RSB is set to logic 1.
PUHF is ‘OFF’, which means that the UHF oscillator and
the UHF mixer are switched off. Consequently, the VHF
oscillator and the VHF mixer are switched on. PVHFL and
PVHFH are ‘OFF’, which means that the VHF tank circuit
is working in the VHF I sub-band. The tuning amplifier is
switched off until the first transmission. In that case, the
tank circuit in VHF I is supplied with the maximum tuning
voltage. The oscillator is therefore working at the end of
the VHF I sub-band.
