Ksz80 Ob S4lv02 Datasheet

Given the ambiguous part string, treat this as either:

| Component | Function | Voltage | Interface | Package | Datasheet Link (Microchip/ST) | |-----------|----------|---------|-----------|---------|-------------------------------| | KSZ8081 | 10/100 Ethernet PHY | 3.3V | RMII | QFN-24 | Microchip KSZ8081 | | 24LC02 | 2Kbit I²C EEPROM | 1.8V-5.5V | I²C | SOIC-8, TSSOP-8 | Microchip 24LC02 | | M24C02 | 2Kbit I²C EEPROM | 1.8V-5.5V | I²C | SOIC-8, TSSOP-8 | ST M24C02 |

This is the most cryptic part. It does not align with standard Ethernet PHY naming conventions. However, there are two strong interpretations:

Interpretation A (OEM House Number): Large OEMs (like Cisco, Siemens, Bosch, or automotive suppliers) often mark chips with their internal part numbers (House Numbers). "S4LV02" could be:

Interpretation B (E2PROM or Memory Device): The suffix "LV02" strongly resembles a Serial EEPROM part code (e.g., 24LC02 = 2Kbit I2C EEPROM, or 93C46). "LV" denotes Low Voltage (1.8V to 5.5V). Could the searcher actually be looking for a 2Kb Low Voltage Serial EEPROM with a "KSZ80" topmark? Unlikely, but possible if a hybrid module contains both.

Interpretation C (Optical Module – SFP/SFF): "OB" might stand for "Optical Bi-directional" and "S4LV02" could be an internal laser driver identifier for an SFP (Small Form-factor Pluggable) module using a KSZ Ethernet controller. This is common in fiber media converters.

KSZ9031RNX - Gigabit Ethernet Transceiver with RGMII Support

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

The keyword "KSZ80 OB S4LV0.2" does not refer to a standalone semiconductor component like a typical Ethernet transceiver. Instead, it is the identifying marking for a T-CON (Timing Controller) board typically used in Sony BRAVIA LCD televisions, most notably the Sony KDL-40R470A

The term "KSZ80" in this context is part of the board’s silk-screen assembly number, and it should not be confused with the Microchip KSZ8081 series of Ethernet PHYs, which share a similar prefix but serve entirely different functions. Overview of the KSZ80 OB S4LV0.2 T-CON Board

The T-CON board acts as the "brain" of the display panel. It receives video data from the television's main logic board (via LVDS cables) and translates it into the specific timing signals required by the Source and Gate drivers to activate the individual pixels on the LCD. Primary Application: Used extensively in the Sony KDL-40R470A and related 40-inch LED/LCD models.

Board Markings: KSZ80 OB, S4LV0.2, and often secondary identifiers like LJ94-25257D LJ94-25482B

Role in TV Repair: This board is the first suspect when a TV has sound but no picture, or shows vertical/horizontal lines and distorted colors. Technical Specifications and Connectivity

While a full "datasheet" in the semiconductor sense isn't public (as these are proprietary Sony/Samsung parts), repair technicians rely on the following technical characteristics: Specification Input Interface Dual-channel LVDS (Low-Voltage Differential Signaling) Compatible Screen Size 40-inch LED/LCD Panels Major ICs

Typically includes a Samsung or Sony proprietary timing controller chip Power Inputs 12V (VCC), VGH, VGL, and AVDD (Analog Supply) Status Indicators

Surface-mount LEDs (on some revisions) to indicate power-good status Troubleshooting Common Faults

If you are searching for this board's datasheet to repair a faulty television, look for these common failure points:

SMD Fuse Failure: The most common issue is a blown surface-mount fuse (often labeled F1) near the LVDS connector. If this fuse is open, the board receives no power, resulting in a black screen despite a working backlight.

Gamma IC Failure: Distorted or "washed out" colors are often caused by a failing Gamma IC (AS15-F or similar) which manages the reference voltages for color accuracy.

VGH/VGL Voltage Issues: Using a multimeter, technicians check for VGH (typically +20V to +30V) and VGL (typically -5V to -10V). If these are missing, the screen will likely remain blank or display a slowly fading image. Where to Source Parts

Because these boards are specific to certain TV models, they are typically found as salvaged or refurbished parts rather than new retail items. You can find listings for this specific board on eBay or Kupindo. Given the ambiguous part string, treat this as

The Microchip KSZ80 series—specifically the KSZ8081 and its close relatives like the KSZ8041 and KSZ8091—represents a foundational line of single-chip 10/100 Ethernet physical layer (PHY) transceivers designed for low power and small footprints.

While "OB S4LV02" often appears on physical package markings as a manufacturing or internal tracking code, the technical behavior of the chip is defined by the KSZ8081 datasheet. Key Technical Specifications

The KSZ8081 is a highly integrated solution that simplifies board design by including several components on-chip.

Ethernet Standards: Supports 10BASE-T and 100BASE-TX IEEE 802.3 compliance. Media Access Control (MAC) Interface:

KSZ8081MNX: Uses the standard MII (Media Independent Interface).

KSZ8081RNB: Uses the RMII (Reduced Media Independent Interface) v1.2, which halves the number of data lines to save space.

Power Efficiency: Features a built-in 1.2V regulator for the core, allowing the entire chip to run off a single 3.3V supply.

Diagnostics (LinkMD®): Uses Time-Domain Reflectometry (TDR) to pinpoint cable faults like shorts or opens, making it a favorite for industrial troubleshooting.

Protection: Includes ±6 kV HBM ESD protection on the differential pairs. Popular Applications

Because of its small size (available in 24-pin or 32-pin QFN packages), this series is standard in: Industrial Controls: For reliable factory floor networking. IP Cameras and Set-top Boxes: Where space is at a premium.

Game Consoles and IP Phones: For high-volume consumer electronics.
