A direct search for a unified datasheet for "KSZ80 OB S4LV02" will not return a single file. This is because "KSZ80 OB S4LV0.2" is . Instead, it is an identifier found physically printed on the T-con board of a specific generation of 40-inch LCD televisions.
Place a as close as possible to the VDD_CO (Core Voltage) pin. ksz80 ob s4lv02 datasheet
Ultra-low active power dissipation (~175 mW).
Assert the physical RST_N pin low for at least the minimum duration specified in the datasheet (typically 100 µs), then pull high.
Beyond hardware strapping pins (such as setting the primary PHY address via pull-up or pull-down configuration resistors), full customization of the chip requires reading and writing to registers through the and Management Data Clock (MDC) serial bus.

revision, it represents the "brain" of a television's display panel. The Story of a TV’s Revival
Integrated circuit tops often use multi-line abbreviated codes. "S4LV02" or similar string segments usually correspond to internal trace codes, silicon revisions, assembly years, or specific production batch variants certified for standard or industrial temperature ranges. Instead, it is an identifier found physically printed
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.
"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.
Because it function as a built-in or detached companion block to specific LCD/LED panels (often paired with Samsung or Sony native glass), tracking down a standalone components datasheet can be difficult. This technical overview serves as an extensive datasheet guide, detailing the board’s architecture, pin functions, critical voltage reference test points, and actionable troubleshooting steps.
