: Provides TDR-based cable diagnostics to identify faulty copper cabling, such as shorts or open circuits. Wake-on-LAN (WOL)

Because "KSZ80 OB S4LV02" appears ambiguous or possibly truncated, treat the above as a structured guide to what an official datasheet would contain and how to proceed. For a precise datasheet, provide the exact marking from the chip (full line of text), the package type, or an image of the IC; with that I can help locate the manufacturer datasheet or recommend close substitutes.

Supports digital I/O voltages of 1.8V, 2.5V, or 3.3V. Common Device Variants

Operates on a single 3.3V supply, featuring an integrated 1.2V LDO regulator for the core.

The is a robust, cost-effective solution for adding wired Ethernet to embedded designs. Its support for both MII and RMII, combined with Auto-MDIX and internal termination, makes it a versatile choice for space-constrained and power-sensitive applications.
