詳細說明

TB1227BN is a triple video driver integrated circuit manufactured by Toshiba. It is specifically designed for use in CRT display applications. The chip features three high-speed video amplifiers that can output RGB signals with a bandwidth of up to 180MHz. This allows for high-quality, distortion-free video signals to be displayed on a CRT monitor.TB1227BN also includes features such as DC restoration circuitry, which helps to maintain consistent black levels in the video signal. This ensures that images displayed on the monitor have proper contrast and clarity. The chip also has a built-in clamp function, which helps to stabilize the DC level of the video signal, preventing unwanted distortion.In addition, TB1227BN has a small package size and low power consumption, making it suitable for use in compact CRT displays and reducing energy costs. The chip is also compatible with both 3.3V and 5V power supplies, providing flexibility for various system designs.

常見問題解答

What is TB1227BN?

The TB1227BN is a vertical deflection output IC (integrated circuit) designed for CRT (cathode ray tube) televisions. It is commonly used to drive the vertical deflection coils in the CRT display, controlling the vertical scanning of the electron beam.

How Does TB1227BN Work?

The TB1227BN works by receiving vertical deflection signals from the TV's circuitry and generating the necessary current to drive the vertical deflection coils. This current causes the electron beam to move vertically across the screen, scanning the image line by line to create the visual display on the CRT screen.

How Many Pins does TB1227BN have and What are the Functions of the Pinout Configuration?

The TB1227BN is typically housed in a multi-pin SIP (Single In-line Package) or DIP (Dual In-line Package). The pinout configuration includes:

  • Yoke: Connects to the vertical deflection coil of the CRT.
  • Deflection Signals: Receives vertical deflection signals from the TV's circuitry.
  • Ground: Provides connection to the ground reference of the circuit.
  • Power Supply: Requires a power supply connection for operation.

What are the Pros and Cons of TB1227BN?

Pros:

  • Specifically Designed for CRT TVs: Tailored for vertical deflection control in CRT televisions.
  • Integral for Vertical Scanning: Essential for proper vertical scanning of the electron beam in CRT displays.
  • Reliable Performance: Offers stable and reliable vertical deflection functionality.
  • Industry Standard: Widely used in traditional CRT TV designs.

Cons:

  • Obsolete Technology: With the decline of CRT TVs, the TB1227BN may be less commonly used in modern designs.
  • Limited Application: Strictly designed for vertical deflection in CRT displays, limiting versatility.

Are There Any Equivalents/Alternatives to TB1227BN for Recommendation?

Due to the specialized nature of vertical deflection ICs for CRT TVs, there may not be direct equivalents to the TB1227BN. However, alternatives for vertical deflection in CRT displays may include ICs from other manufacturers like Sanyo, Sony, or Samsung.
