s FUNCTION DESCRIPTION

1. Synchronous Mode

1) Horizontal synchronous

There are two synchronous input terminals, first is pin-51 (SYNCIN1) and other is

pin-49 (SYNCIN2). There are no difference, and selected by pin-50 (SYNCSW).

The composite-synchronous/synchronous and Y signal input to pin-51/49 either. The

input (pin-51/49) signal is separate by horizontal and vertical synchronous signal. The
AFC loop consists of horizontal synchronous signal and 1/32 signal divided 32fH VCO
output signal without any adjustment. The pin-56 (CSYNCOUT) is composite-synchronous
signal output selected by pin-50, and open collector type.

2) Vertical synchronous

The countdown circuit reset the data to use vertical synchronous signal and 32f

VCO

output. This VD pulse is stable even if the weak-signal.

2. Color Signal Play Mode

1) ACC Circuit

The chroma signal input to pin-14 (CIN), and detect the burst-signal through the HPF

circuit, and controlled stable burst-signal feedback from demodulate output. When the
pin-14 is GND level, the mode is composite input, and pin-19 (VIDEOIN) composite-video
signal input to ACC circuit.

2) APC Circuit, and VCXO

The burst signal level of chroma is constant by ACC circuit. The PLL circuit consists of

VCXO and locked burst signal. The pin-13 (TINT) input DC voltage adjust the VCXO
phase, and adjust the demodulate axis. When the pin-13 is GND, the mode is PAL, and
only accepts analog RGB input.

3) Color Killer

The chroma signal is output to demodulator when PLL locked, and the color killer is

�42dB.

4) Color Circuit

This circuit adjusts the color TINT. The pin-15 (COLOR) adjusts the chroma signal

range from ACC circuit. This signal demodulator without burst signal by burst gate pulse
(BGP).

5) DEMOD

This DEMOD circuits demodulate color differential signal after the ACC circuit. The

RGB signal consists of color differential and Y signal by matrix circuit, and input to Int./Ext.
signal switches.

NJW1301

- 33 -

3. Y-signal Mode

1) TRAP

The composite video signal input to pin-19 (VIDEOIN) without the chroma by TRAP

circuit. The TPAP frequency is 3.58MHz, and not through when Y/C input mode.

2) Picture Circuit

The Y/composite-signal input to pin-19 (VIDEOIN) without the synchronous signal. The

pin-25 (PICTURE) adjusts the frequency characteristic around 2MHz and emphasizes the
outline. The pin-25 level emphasizes outline depend on the DC voltage. The Y-signal
output pin-22 (YOUT), and input to pin-24 (YINH) through the external second differential
circuit.

4. INT./EXT. Signal Switch Mode

The analog RGB signal (0.7V

P-P

typ.) input to pin-29, pin-31, and pin-33, and these signal

clamps pedestal. The ext-signal select Y/C-signal or Int-signal by pin-26 (SW).

5. RGB SIGNAL MODE

1) Contrast

The pin-27 (CONTRAST) adjusts the all of RGB signal, which is black-to-white range.

Amplifier

This circuit is non-liner amplifier to adjust the RGB signal equal to the luminous

characteristics. There is two-point adjustment for accurate correction. The pin-38 (VG1)
adjusts low side, and the pin-39 (VG2) adjusts high side.

]

3) Sub

Circuit

This circuit adjusts

characteristics of B/R signal, and sub

adjusts white-balance for

the monitor. The pin-38 (SUBVG1R) and pin-36 (SUBVG2R) adjust low side with R-signal
and high side with

characteristics. The pin-39 (SUBVG1B) and pin-37 (SUBVG2B)

adjust low side with B-signal and high side for

characteristics. These terminal controls

R-signal and B-signal separately.

4) Bright

The pin-27 (CONTRAST) clamps the pedestal after the brightness adjustment (black to

black).

5) Side Black

The side-black circuit output black level, when the mode is black mask for wide picture.
The RGB signal is black level when pin-42 (SIDEBLACK) input signal is low period only.

6) Output Amplifier

The pin-41 (FRP) input to the timing pulse with inverting RGB output, and output the

inverting RGB signal per every 1H. The RGB outputs are:

FRP-High: Non-inverting output
FRP-Low: Inverting output
The center voltage is preset to half of Vcc.

6. Common Driver

The LCD common invert RGB output, and the pin-4 (VCOMIN) input to the common driver

signal (5V

P-P

). The pin-2 (VCOMAMP) adjusts the range, the pin-5 (VCOMCENT) adjusts

the center voltage. The pin-7 (VCOMOUT) connect external discreet buffer, and feedback
the buffer output for pin-6 (VCOMFB).

7. PWM Signal for Backlight

The pin-60 (PWMOUT) output the PWM signal for LCD backlight, open collector type, and

connect pull-up resistor. The pin-58 (PWMOUT) adjusts the PWM duty.
