Tsum1pfr-lf Datasheet Jun 2026

Engineers and repair technicians frequently look up the to analyze its pin layout, electrical limits, and built-in scaling properties when designing display driver boards or troubleshooting legacy flat-screen monitors. 1. Technical Architecture Overview

While the absolute pin mapping depends on the exact schematic layout of the OEM driver board, the pin arrangement is split into specialized functional groups:

The is your roadmap to successfully integrating this component into your workflow. By verifying the electrical ratings, understanding the pinout, and confirming the package dimensions, you can avoid costly mistakes and ensure your circuit functions as intended.

The TSUM1PFR-LF combines several video processing blocks into a single piece of silicon. By integrating these functions, manufacturers can design exceptionally small and cost-effective driver board PCBs. Tsum1pfr-lf Datasheet

: Translates various incoming video resolutions up or down to match the native resolution of the connected TFT LCD panel.

Small-sized LCD TVs focusing on high-definition signal processing.

The TSUM1PFR-LF is available through specialized chip suppliers and open-market distribution networks: Engineers and repair technicians frequently look up the

| Pin No. | Symbol | Function Description | |---------|--------|----------------------| | 1 | VIN | Input voltage supply. Bypass with 1µF ceramic capacitor to GND. | | 2 | GND | Ground connection. Connected to thermal pad if present. | | 3 | EN | Enable pin. Active high (logic >1.2V). Tie to VIN if unused. | | 4 | NC / BYP | No connect or bypass capacitor pin for noise reduction. | | 5 | VOUT | Regulated output voltage. Output capacitor (1µF to 10µF) required. |

communication lines (SDA/SCL) for microcontrollers, UART pins for flashing system firmware, crystal oscillator pins (XTAL_IN/XTAL_OUT), and a dedicated system reset pin (RESET). System Circuit Diagram Considerations

The core application of the is converting a higher DC bus (e.g., 5V USB or 3.7V Li-Ion battery) to a clean lower voltage (e.g., 3.3V for a microcontroller or 1.8V for a sensor). : Translates various incoming video resolutions up or

The TSUM1PFR-LF uses an package with 64 pins. The pins are arranged around the four sides of the chip, facilitating easy surface-mount soldering on a printed circuit board (PCB).

The integrated high-speed triple-ADC digitizes analog RGB video signals received from classic VGA (D-Sub) input interfaces. The accompanying system PLL ensures precise clock regeneration, preventing pixel jitter and alignment errors. 2. Scaling & De-interlacer Engine
