The reference KSZ80-0B-S4LV02 corresponds to a TV Scaler PCB Board

used in LED and LCD television repairs. While the board name begins with "KSZ80," it is distinct from the standalone Microchip KSZ80 series Ethernet PHY integrated circuits, though it likely utilizes a component from that family for network functionality. Board Overview: KSZ80-0B-S4LV02 This board is a specialized Panel Scaler PCB

designed for managing the display and signal processing within a television. Application : LED and LCD TV repair and assembly.

: Acts as the interface between the main TV motherboard and the display panel (scaler board). : Original replacement part for compatible TV models. Integrated Component: KSZ8081 Series Features Since these boards often feature Microchip's

Ethernet transceivers for smart TV connectivity, the following technical specifications generally apply to the underlying network hardware on such boards: Ethernet Standard

: Single-chip 10Base-T/100Base-TX IEEE 802.3-compliant transceiver. Data Rates : Supports 10 Mbps and 100 Mbps operations. : Typically supports

(Reduced Media Independent Interface) for connection to host processors. Power Supply

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

: Automatically detects and corrects crossover or straight-through cable connections. LinkMD® Diagnostics ksz80 ob s4lv02 datasheet

: TDR-based cable diagnostics to identify shorts, opens, or cable faults. Wake-on-LAN (WOL) : Support for remote wake-up via specific network packets. Diagnostics

: Includes loopback modes and parametric NAND tree support for manufacturing fault detection. Microchip Technology Common Variants on Scaler Boards

Depending on the specific TV model, you may encounter different versions of the underlying PHY chip: KSZ8081RNA

: Optimized for space-constrained designs, often used in smaller 24-pin QFN packages. KSZ8081RNB

: Features more dedicated pins for LED status outputs and hardware configuration strapping. Microchip Technology wiring diagram for this specific scaler board, or do you need a list of compatible TV models for replacement? KSZ8081 | Microchip Technology

I’m unable to provide a complete write-up or datasheet for the part number "ksz80 ob s4lv02" because it does not correspond to a standard, publicly released integrated circuit or component from major manufacturers (such as Microchip/KSZ series, Texas Instruments, NXP, etc.).

Here’s why:

To get the right datasheet:

If you meant a different part number (e.g., KSZ8081RNACA, KSZ8041, or 24LV02), I can provide a full datasheet summary for that instead. Let me know how you’d like to proceed.

The identifier KSZ80_0B_S4LV0.2 refers to a specific Scaler PCB Board (also known as a Panel Scaler) used in the internal circuitry of various LED and LCD televisions.

While "KSZ80" also appears in the model numbers for Microchip/Micrel Ethernet transceivers (like the KSZ8081 or KSZ8041), this specific board string is associated with TV display hardware rather than a standalone networking chip. Part Details Part Type: LED/LCD Scaler Board (Panel Scaler PCB). PCB Number: KSZ80_0B_S4LV0.2.

Function: This board is responsible for "scaling" input signals to match the native resolution and timing of the TV's display panel.

Availability: These are typically sold as replacement parts by electronics repair specialists like Great Bharat Spares for repairing display issues in compatible TV models. Related Component (Ethernet PHY)

If you are looking for a "KSZ80" datasheet for a single chip rather than a TV board, you likely mean one of the following Microchip Ethernet PHYs:

KSZ8081: A single-chip 10/100 Ethernet transceiver often used in game consoles, IP TVs, and set-top boxes.

KSZ8041: A similar 10/100 Physical Layer Transceiver that supports MII/RMII/SMII interfaces.

Note: If you are performing a TV repair, ensure the PCB number matches exactly, as scaler boards are highly specific to the panel they drive. Are you trying to repair a specific TV model, or KSZ8081MNX/RNB Data Sheet - Microchip Technology

It sounds like you’re looking for a datasheet or technical information on a part labeled “KSZ80 OB S4LV02” — possibly a memory chip (S4LV02 suggests a 2 Mbit SRAM or similar) combined with a KSZ80 marking (which could be a network controller or a custom ASIC). Look at the chip under a microscope or magnifying glass

However, I should be upfront: there is no widely known standard component with the exact string “KSZ80 OB S4LV02” in official datasheet databases (e.g., from Micron, Cypress, ISSI, Microchip, etc.).

Here’s a breakdown of what you might be dealing with — and a possible story behind the label:

Please reply with:

With that, I can pinpoint the exact datasheet for you.

Would you like general datasheets for 24LC02 (2Kbit I²C EEPROM) or KSZ80xx series Ethernet PHY as a starting point?

The string "ksz80 ob s4lv02" is a common misreading of the laser markings on the chip package, where:

Below is a technical write-up for the Microchip (formerly Micrel) KSZ8081 Ethernet PHY, based on the standard datasheet specifications.

OEMs sometimes disable standard JTAG or MII pins. The "S4LV02" might refer to a custom OTP (One Time Programmable) configuration loaded during manufacturing. In this case, the electrical characteristics, register maps, and timing diagrams are identical to the KSZ8081 datasheet. Only the strapping options (PHY address, LED modes) differ.

The KSZ8081 is a single-supply 10Base-T/100Base-TX Ethernet Physical Layer Transceiver (PHY) manufactured by Microchip Technology (formerly Micrel).
