5 V mixers/oscillators and synthesizers for
cable TV and VCR 2-band tuners
TDA6402; TDA6402A;
TDA6403; TDA6403A
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 ‘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.
If the first sequence transmitted to the device
has 18 or 19 bits, the reference divider ratio is set to 512
or 1024, depending on the sequence length.
If the sequence has 27 bits, the reference divider ratio is
fixed by RSA and RSB bits (see Table 8).
Fig.4 Normal mode; 18-bit data format (RSA = 1).
