"The datasheet," the taller one said. His voice sounded like two stones grinding together. "It is property of the Aegis Corporation. You are in possession of a trade secret with a Tier-1 lethality clearance."
The KSZ8081RNB (often referred to in project BOMs as the KSZ80 OB S4LV0.2) is a single-supply 10Base-T/100Base-TX Ethernet physical layer transceiver. This specific hardware revision is widely used in industrial networking, automotive interfaces, and high-performance embedded systems.
It handles the high-speed LVDS (Low-Voltage Differential Signaling) data, ensuring accurate color reproduction and motion handling.
In both cases, this board works in conjunction with a 40-inch LCD panel. The Sony and JVC TVs likely use a similar panel assembly. Specifically, the Sony KDL-40R473A model uses an , which is paired with this T-Con board. Ksz80 Ob S4lv0.2 Datasheet
You can find the "KSZ80_OB_S4LV0.2" marking on the physical T-Con board itself, often near the model number of the panel. On this board, you will also find other supporting components:
I noticed a few people searching for this specific revision string, so I wanted to share a quick resource guide and a clarification for anyone designing with this PHY.
Desolder the shorted CD8 MLCC and clean the footprint. Replace it with an identically spec'd high-voltage surface-mount capacitor (typically rated at 25V or 50V operational tolerances) to safely restore the +17V AVDD line and recover the display. Panel Gate Driver Faults "The datasheet," the taller one said
The differential analog signals connect directly to the network magnetics (transformer): : Transmit differential pair. RXP / RXN : Receive differential pair. 3. Register Mapping and Software Configuration
Locate the surface-mount input fuse (usually labeled ) near the LVDS input connector interface.
To continue troubleshooting, would you like help isolating typically shorts out on this board, or do you need a step-by-step guide for injecting external voltages into the VGH/VGL test points? Share public link You are in possession of a trade secret
Note: There’s no widely known or standard component named “Ksz80 Ob S4lv0.2” in mainstream electronics databases; the following is a structured, comprehensive example datasheet-style text assuming this is a semiconductor/networking IC part number variant (reasonably modeled on typical KSZ-series Ethernet switches and related devices). Treat this as a template you can adapt if you provide an official part number or a PDF.
Additionally, the chip supports auto-negotiation to automatically select the highest link speed (10/100 Mbps) and duplex mode (half/full). Pinout and Layout Considerations
