Function
Ground for all drivers other than the 75Ω driver.
Analog R signal input. Drive at low impedance.
Analog G signal input. Drive at low impedance.
Analog B signal input. Drive at low impedance.
This pin is not connected inside the IC.
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.
Selecting the type of color TV signal output. The high level selects NTSC, the low level PAL. Internally
pulled up to 50kΩ.
Burst timing output. Burst timing is generated inside the IC when the subcarrier and composite
synchronization signal.
This pin is not connected inside the IC.
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 100kΩ.
Composite synchronization signal output.
Power supply pin for all except the 75Ω driver.
This pin is not connected inside the IC.
This pin is not connected inside the IC.
Chroma signal output. Internal 75Ω driver.
Luminance signal output. Internal 75Ω driver.
Attached luminance trap filter. Attaching a trap filter reduces chroma signal cross-color caused
by the luminance signal. Output impedance is approximately 2kΩ.
This pin is not connected inside the IC.
Power supply pin for the 75Ω driver.
Color TV signal output. Internal 75Ωdriver.
Analog B signal output. Internal 75Ω driver.
Analog G signal output. Internal 75Ω driver.
Analog R signal output. Internal 75Ω driver.
Ground for the 75Ω driver.
