If you can share a of the chip marking and package, I can likely identify it exactly. Would you like help searching a specific manufacturer database instead?
: These chips offer features like Wake-on-LAN (WOL) , Energy Efficient Ethernet (EEE) , and LinkMD® cable diagnostics, which help the TV maintain stable internet connections for streaming services. Summary of Technical Specifications 1 indicates link parameter resolution is finished
The reference KSZ80-0B-S4LV02 corresponds to a TV Scaler PCB Board
processes Low-Voltage Differential Signaling (LVDS) inputs from the motherboard and translates them into Mini-LVDS or RSDS (Reduced Swing Differential Signaling) outputs. These outputs directly drive the source and gate driver ICs on the panel's COF (Chip-on-Film) ribbons. Core Component Sub-Systems
is a critical hardware component commonly known as a Timing Controller (T-Con) board, widely integrated into 40-inch television displays such as the Sony KDL-40R470A . Serving as the bridge between the television's main logic board and the liquid crystal display (LCD) glass panel, this module manages pixel refresh synchronization, voltage regulation, and signal translation. (Ignored if Auto-Negotiation is enabled)
The host processor communicates with the KSZ8081 via the MDIO/MDC serial interface. This allows the host to read link status, speed, and duplex, or to write configuration changes.
Single 3.3V power supply with integrated 1.2V LDO regulator for the core logic.
, you can provide a 50 MHz reference clock or use a 25 MHz crystal to have the PHY generate the 50 MHz clock for the MAC. Verify Register , bit 7 for default clock settings. Hardware Strapping
The most reliable way is to search the entire string of characters as you see it on the chip.
