Ksz80 Ob S4lv02 Datasheet Fixed -

The reference KSZ80-0B-S4LV02 corresponds to a TV Scaler PCB Board

Interpretation A (OEM House Number): Large OEMs (like Cisco, Siemens, Bosch, or automotive suppliers) often mark chips with their internal part numbers (House Numbers). "S4LV02" could be: ksz80 ob s4lv02 datasheet

: Single-chip 10Base-T/100Base-TX IEEE 802.3-compliant transceiver. Data Rates : Supports 10 Mbps and 100 Mbps operations. : Typically supports The reference KSZ80-0B-S4LV02 corresponds to a TV Scaler

They are two different chips combined in a BOM or silkscreen label “KSZ80 OB S4LV02” as a board assembly code or handwritten note. Use manufacturer part marking lookup tools : Integrated

Use manufacturer part marking lookup tools:

Integrated LDO Regulator: The chip includes a built-in 1.2V regulator to power its core, allowing the entire device to operate from a single 3.3V supply.

Debugging and bring-up checklist

Verify correct supply voltages and decoupling.
Check reset and clock sources are active and within spec.
Confirm pin strapping/config options are set for intended mode.
Use logic analyzer to capture interface signals and verify timing.
Check power/current draw against expected values.

Originality: When sourcing this part, ensure it is a 100% original match to the PCB number to maintain the TV's original display quality.
