This is not a standalone part number. It is a specific package marking for Microchip Technology’s highly popular or KSZ8041 family of single-chip 10Base-T/100Base-TX Ethernet physical layer (PHY) transceivers. Deconstructing the Marking Code This is not a standalone part number

To achieve low electromagnetic emission footprints—such as those characterized by the automotive-qualified Microchip KSZ8061 with Quiet-WIRE® filtering —place decoupling capacitors close to the physical supply pins. Use a combination of Use a combination of To troubleshoot a suspected

To troubleshoot a suspected KSZ80 OB S4LV0.2 board, use a digital multimeter to verify the following standard test pads against ground: Test Point Label Expected Voltage Range Primary Function Fault Indicator Main DC Input from Motherboard on downstream side indicates short circuit or blown fuse. VCC / VDD T-Con Core Logic Power Processor will not boot if missing. AVDD Source Driver Analog Rail Distorted, washed-out images or blank screen. VGH Gate Turn-On Voltage Slow refresh rate, vertical ghosting, or no image. VGL Gate Turn-Off Voltage Excessive image retention or flickering streaks. Step-by-Step Practical Repair Methodology

Assert the physical RST_N pin low for at least the minimum duration specified in the datasheet (typically 100 µs), then pull high.
