Ground for the 75
driver.
Color subcarrier input. Input a 3.579545MHz
(
NTSC) or 4.433619MHz (PAL) sign wave or pulse wave
(50% duty). Do not exceed the range of GND-Vcc.
Burst timing output. Burst timing is generated inside the IC when the subcarrier and composite
synchronization signal.
Selecting the type of color TV signal output. The high level selects NTSC, the low level PAL. Internally
pulled up to 50k
.
Attached luminance trap filter. Attaching a trap filter reduces chroma signal cross-color caused
by the luminance signal. Output impedance is approximately 2k
.
Function
Composite synchronization signal input. When the low level is input, the synchronization signal is output to
both YOUT and VOUT, and inputs to RIN, GIN and BIN are clamped. This pin is internally pulled up to 100k
.
