Oscillation method control bit
In the
μ
PD6464A and 6465, the oscillation method can be selected from
×
4 multiplication oscillation and 4f
SC
crystal
oscillation with the oscillation method control command.
When
×
4 multiplication oscillation is selected, the f
SC
signal must be input from the FSCI pin. The 4f
SC
signal is
generated from an external LC resonator and an internal circuit of the
μ
PD6464A and 6465. The phase of four-
divided 4f
SC
signal generated via LC oscillation is compared with that of the f
SC
signal that is input to the FSCI pin.
The obtained phase error is converted to a voltage value, and then output from the FSCO pin. In the circuit shown
in
8. APPLICATION CIRCUIT DIAGRAM (1) In
×
4 multiplication oscillation
, the 4f
SC
signal synchronizing with
the external f
SC
signal is generated by changing the capacitance of varactor diodes with this voltage that is based
on a phase error.
When 4f
SC
crystal oscillation is selected, the FSCI and FSCO pins are not used. These pins should be connected
as follows.
FSCI pin (pin 9)
FSCO pin (pin 10) : Leave open.
: Connect to GND or V
DD
.
Remark
The scanning method in the internal video signal mode is non-interlacing. With the NTSC and PAL-
M methods, the number of scanning lines is 263. With the PAL and PAL-N method, it is 312.
