Ksz80 Ob S4lv0.2 Datasheet !!top!! 🔥

The KSZ80-0B-S4LV0.2 is not a standalone integrated circuit datasheet but rather a specific Scaler PCB Board (also known as a Panel Scaler PCB or T-Con interface board) commonly found in Sony LED/LCD TVs, such as the Sony KDL-40R473A KDL-40R450A Technical Overview

This board acts as the critical bridge between the TV's main logic board and the actual LCD panel. It processes image enhancement signals and distributes the necessary voltages for the display to function. Primary Function: Scaler boards like the KSZ80-0B-S4LV0.2

manage the timing and driving of the pixels on the LCD glass.

Voltage Requirements: It typically operates on a 12V VCC input and generates secondary voltages for the panel, including: 3.3V: Logic power. VGH / VGL: Gate high/low voltages for pixel switching. AVDD: Analog supply for the source driver. Common Issues and Troubleshooting

In the 40-inch Sony LED series, this board is frequently associated with "No Display" or "Blank Screen" symptoms where the backlight remains functional.

Protection Mode: If an internal short occurs within the gate signals of the glass panel, the DC-DC IC on the KSZ80 board may enter protection mode, causing VGH, VGL, and AVD voltages to disappear.

Temporary Repair Method: Technicians often use a "track cutting" method on the scaler PCB to isolate shorted gate signals (such as CKV1, CKV2, or CKB lines) to restore the picture, though this is often a temporary fix.

Availability: These boards are often sourced from specialized electronics retailers as pre-owned parts, as they are typically tied to specific panel models and are not sold as generic components. Buy Original LED TV Scaler PCB Board KSZ80-0B-S4LV0.2 Ksz80 Ob S4lv0.2 Datasheet

6. Application Schematic Guidelines

To ensure signal integrity for the "S4lv0.2" variant, the following layout rules apply:

1. Magnetics: Must be placed within 1 inch of the PHY TRD/RDX pins.
2. Termination: The KSZ80 series typically integrates 50Ω termination resistors. External termination is usually not required unless specified by specific silicon errata.
3. Decoupling: Place 0.1µF and 10µF capacitors as close as possible to VDDA and VDDIO pins.
4. Grounding: The exposed pad (EPAD) on the bottom of the QFN package must be soldered to the ground plane for thermal relief and electrical grounding.
