CXA2050S
5. Deflection block register
AFC-MODE (2) : AFC loop gain control (PLL between H SYNC and H VCO)
0h = H free run mode
1h = Small gain
2h = Medium gain
3h = Large gain
FH-HI
(1)
: H oscillator frequency fixation ON/OFF switch
(Set to ON mode at power-on.)
0 = H oscillator frequency fixation OFF AFC normal mode
1 = H oscillator frequency fixation ON Oscillator frequency fixed to maximum value
(approx. 16.2kHz)
V FREQ
V OFF
(1)
(1)
: V frequency mode setting
0, 1h = Automatic identification
2h = Forced mode (50Hz)
3h = Forced mode (60Hz)
: V sawtooth wave oscillation stop ON/OFF switch
(Set to OFF mode at power-on.)
0 = Oscillation stop OFF (V DRIVE– and V DRIVE+: normal output)
1 = Oscillation stop ON (V DRIVE– and V DRIVE+: DC output and DC value vary
according to V POSITION.)
CD-MODE
(1)
: V countdown system mode selector
(Set to automatic selection mode during power-on.)
0 = Non-standard signal mode, standard signal mode and no signal mode
automatically selected
1 = Fixed to non-standard signal mode
(V oscillator frequency is 55Hz during no signal mode "free run".)
CDMODE2
VBLKW
(1)
(2)
: Vertical sync pull-in speed selector
0 = Standard
1 = High speed
: VBLK width control (Blanked pulses after reference pulse. Operates when
JMPSW = 1; blanked pulses after reference pulse fixed to 1H when JMPSW = 0.)
0h = 12H from Bch reference pulse
1h = 11H from Bch reference pulse
2h = 10H from Bch reference pulse
3h = 9H from Bch reference pulse
H-POSITION (4)
V-POSITION (6)
: Horizontal position adjustment (HAFC phase control)
0h = 1µs delay
7h = 0µs
Picture position shifts to right. (Picture delayed with respect to HD.)
Fh = 1µs advance
Picture position shifts to left. (Picture advanced with respect to HD.)
: Vertical position adjustment (V SAW output DC bias control)
0h = –0.09V Picture position drops, V DRIVE+ output DC Down.
1Fh =
0V Center potential: DC 3V
3Fh = +0.09V Picture position rises, V DRIVE+ output DC Up.
