TDA8374A (Single chip TV Processor for Negative modulation IF ) TDA8374 (Single chip TV Processor for Negative & positive modulation IF)
(1)General Description
The TDA8374(A) is
The IC is mounted in a
(2)Feature
•IF
-Vision IF amplifier with high sensitivity and good figures for differential phase and gain
-PLL demodulator with high linearity offering the possibility for (single standard) intercarrier stereo audio application .
-Alignment PLL via I2C
-[TDA8374] Multistandard IF with negative and positive modulation, switchable via I2C
•AUDIO
-Alignment free multi standard PLL audio demodulator (4.5 to 6.5 MHz.)
-Mono volume control
•Video
-Integrated luminance delay line
-Integrated chroma trap and bandpass filters (auto calibrated)
-Asymmetrical peaking circuit in the luminance channel
-Black stretching of non standard CVBS or luminance signals
•Colour
-SECAM interface for application with SECAM
•RGB
-RGB control (brightness, contrast, saturation)
-Black current stabilization and white point adjustment
•Input / Output
-Flexible video source select with CVBS input for the internal signal and two external video inputs(one switchable for CVBS or Y/C).
-The output signal of the video source select is externally available ( also as CVBS when Y/C input is used).
-External audio input.
-Linear RGB input with fast blanking.
•Synchronization and Deflection
-Horizontal synchronization with two control loops and alignment free horizontal oscillator.
-Slow start and slow stop of the horizontal drive output to enable low stress
-Vertical
-Vertical geometry control.
-Vertical drive optimized for DC coupled vertical output stages.
•Control
-Full I2C bus control, as well for customer controls as for factory alignment.
-All automatic controls have an option for forced mode.
•Power consumption
-Low power consumption (900 mW at 8.0 Volts).
•Packaging
