詳細說明
GENERAL DESCRIPTIONThe various versions of the TDA837x series are I2C-bus controlled single-chip TV processors which are intended to be applied in PAL/NTSC (TDA8374 and TDA8375) and NTSC (TDA8373 and TDA8377) television receivers. All ICs are available in an SDIP56 package and some versions are also available in a QFP64 package. The ICs are pin compatible so that with one application board NTSC and PAL/NTSC (or multistandard together with the SECAM decoder TDA8395) receivers can be built. Functionally this IC series is split in to 2 categories: Versions intended to be used in economy TV receivers with all basic functions Versions with additional functions such as E-W geometry control, horizontal and vertical zoom function and YUV interface which are intended for TV receivers with 110° picture tubes.
主要特徵

- Vision IF amplifier with high sensitivity and good figures for differential phase and gain
- PLL demodulator for the IF signal
- Alignment-free sound demodulator
- Flexible source selection with a CVBS input for the internal signal and Y/C or CVBS input for the external signal
- Audio switch
- The output signal of the CVBS (Y/C) switch is externally available
- Integrated chrominance trap and band-pass filters (auto-calibrated)
- Luminance delay line integrated
- A symmetrical peaking circuit in the luminance channel
- Black stretching of non-standard CVBS or luminance signals
- RGB control circuit with black current stabilization and white point adjustment
- Linear RGB inputs and fast blanking
- Horizontal synchronization with two control loops and alignment-free horizontal oscillator
- Slow start and slow stop of the horizontal drive pulses
- Vertical count-down circuit
- Vertical driver optimized for DC-coupled vertical output stages
- I2C-bus control of various functions
- Low dissipation
- Small amount of peripheral components compared with competition ICs.

常見問題解答
What is TDA8374?
The TDA8374 is an integrated TV processor circuit designed for use in PAL and NTSC television systems. It provides a complete solution for television signal processing, including video and sound IF processing, video and sound demodulation, and the processing of luminance and chrominance signals. The TDA8374 is suitable for use in analog TV sets and other video display applications.
How Does TDA8374 Work?
The TDA8374 works by receiving and processing the analog television signal from the antenna or cable input. It includes various stages of signal processing such as IF processing, demodulation, and separation of the luminance and chrominance signals. The processed signals are then output for display on the television screen or further processing by additional video and sound components.
How Many Pins does TDA8374 have and What are the Functions of the Pinout Configuration?
The TDA8374 is housed in a multi-pin package to accommodate its various functions. The pinout configuration includes pins for power supply, input and output connections, and control signals for configuring the device's operation.
What are the Pros and Cons of TDA8374?
Pros:
- All-in-One Solution: Provides a complete solution for processing analog TV signals, reducing the need for external components.
- Flexible Compatibility: Supports both PAL and NTSC television systems, making it suitable for a wide range of applications.
- Integrated Sound Processing: Includes sound IF processing and demodulation for a complete audiovisual solution.
- Cost-Effective: Consolidates multiple functions into a single IC, potentially reducing overall system cost.
Cons:
- Obsolete Technology: As analog TV systems are being phased out in many regions, the TDA8374 may have limited relevance for future designs.
- Limited Interface: May require additional external components for modern video display interfaces such as HDMI or DisplayPort.
Are There Any Equivalents/Alternatives to TDA8374 for Recommendation?
- Alternatives to the TDA8374 include the TDA8361 from STMicroelectronics and the LA76810A from Sanyo (now part of ON Semiconductor).
