Ksz80 Ob S4lv02 Datasheet Jun 2026

You can download the official datasheet directly from the manufacturer's website:

: Single 3.3V power supply with an internal 1.2V regulator for the core. Key Features HP Auto MDI/MDI-X

The closest known part is (Microchip) or S-24C02 (ABLIC) – a 2Kbit I²C serial EEPROM. The “LV” suggests Low Voltage (1.7V–3.6V operation).

Power down the unit and use a digital multimeter in continuity mode. Test the ceramic capacitors arrayed near the main ribbon interface. If a capacitor reads 0 Ohms to ground, desolder and replace it with an equivalent farad rating (typically 10uF, rated to 25V or 50V). 3. Solarized Colors or Distorted Image ksz80 ob s4lv02 datasheet

The string "KSZ80 OB S4LV0.2" is a manufacturer or service part number found printed on the PCB itself or on a barcode sticker attached to the board. It is not a recognized commercial datasheet number for a standard industry part. Variations of this number have been identified in the field:

The T-con (Timing Controller) board bearing the "KSZ80_OB_S4LV0.2" marking is the intermediary between the television's main logic board and the LCD panel.

A Micrel-specific register used to quickly read operational status, manage LED pulse stretching, and toggle power-saving modes. Power down the unit and use a digital

For circuit board diagnostics, focus your manual schematic tracing across these four primary component quadrants:

The hardware addresses are sampled at power-up via strap-in pins (shared with LED functions). Ensure external pull-up or pull-down resistors are set to the correct logic levels expected by your software driver. Inspect Register 0x00 and 0x01

Do not route high-speed digital traces or clocks directly underneath or across the analog differential lines.
