50 MHz reference clock. This can be inputted from an external source or generated by the PHY using a 25 MHz crystal. TXEN: Transmit Enable signal from the MAC. TXD[1:0]: Two-bit transmit data bus.
is an essential responsible for translating incoming video signals into a format that a television’s display matrix can render. Found frequently within mid-sized television panels from manufacturers like Sony and LG, this physical component functions as a bridge between the main T-CON (Timing Controller) circuitry or mainboard and the source drivers of the liquid crystal display.
Instead, the identifier refers to a specific Timing Controller Board (T-CON) used in several models of LCD/LED televisions, particularly older models from Sony and JVC. It is a designated assembly part number for a specific PCB, not the model number of an individual integrated circuit (IC) on the board. The search for this "datasheet" often leads down a rabbit hole of service manuals and replacement part sales, which this article aims to clarify. ksz80 ob s4lv02 datasheet
This article will provide a complete technical breakdown of what "KSZ80 OB S4LV0.2" represents, the components involved, and how to find the accurate technical documents needed for repair and reverse engineering.
The chip contains an internal LDO regulator that drops 3.3V down to 1.2V to power the high-speed digital core. 50 MHz reference clock
Because of its small size (available in 24-pin or 32-pin QFN packages), this series is standard in: : For reliable factory floor networking. IP Cameras and Set-top Boxes : Where space is at a premium.
1 means the network link is valid and established; 0 means the link is down. Register 1Fh: PHY Control Register TXD[1:0]: Two-bit transmit data bus
For faster development, the KSZ8081RNB-EVAL evaluation board is available to test functionality and configuration before finalizing the PCB design. Conclusion
Use the electrical and timing specifications from that document, and consult the specific board’s hardware manual for the strapping configuration of "OB S4LV02."
: Check the appendix of the general transceiver data sheets to match your specific top-marking code to the corresponding tracking lot, packaging compound, or lead-free classification.
The KSZ8081 can be configured for several distinct operational modes:
