The most reliable way is to search the entire string of characters as you see it on the chip.
The exposed pad (EPAD) underneath the QFN package must be soldered securely to the main system ground plane. This is critical for both electrical grounding and thermal dissipation. 5. Software Configuration via MDIO/MDC Registers ksz80 ob s4lv02 datasheet
: Supports remote wake-up via magic packets or custom packet detection, ideal for power-managed systems. Interface and Physical Specs Interface Options : Most models support standard (Media Independent Interface) or
The device operates on a single supply voltage (typically 3.3V or 1.8V/2.5V with specific configurations).
A typical circuit design using the KSZ8081 involves the following connections:
Use the electrical and timing specifications from that document, and consult the specific board’s hardware manual for the strapping configuration of "OB S4LV02." This is critical for both electrical grounding and
: Features standard power-down and Energy-Detect Power-Down , which reduces consumption when the link is idle.

It sounds like you’re looking for a or technical information on a part labeled “KSZ80 OB S4LV02” — possibly a memory chip (S4LV02 suggests a 2 Mbit SRAM or similar) combined with a KSZ80 marking (which could be a network controller or a custom ASIC).
From a hardware integration perspective, the KSZ8081MLX simplifies the Bill of Materials (BOM). It features on-chip termination resistors for the differential pairs, eliminating the need for external components that would otherwise occupy valuable PCB space. The device also includes integrated LDO controllers, allowing it to operate from a single 3.3V supply while generating the necessary core voltages internally.
The text printed on the chip package—specifically lines like "KSZ80" followed by internal tracking, step, or package codes like "OB S4LV02"—typically points directly to the or KSZ8001 family of Ethernet PHYs. Interface and Physical Specs Interface Options : Most
Used in switches, routers, and broadband devices.
