Ksz80 - Ob S4lv0.2 Datasheet Better
Because this is a proprietary component manufactured for specific display panels, a standard public IC-style datasheet (like those for Microchip KSZ80 Ethernet transceivers) does not exist for the board assembly itself. Instead, technical information is found via board-level specifications and spare part listings. Core Specifications & Use Case Part Type: LED/LCD Scaler Board / Panel Scaler PCB.
Physical Layer: 10Base-T and 100Base-TX support.Interface: RMII (Reduced Media Independent Interface) with a 50MHz reference clock output.Power Supply: Single 3.3V operation with an integrated 1.2V LDO regulator.Power Consumption: Extremely low, typically <180mW during active 100Base-TX transmission.Package: 32-pin QFN (5mm x 5mm), ideal for space-constrained IoT devices. Diagnostic Features and Link Management
PHY Transceiver
The integrated PHY transceiver provides reliable and efficient data transmission over the Ethernet cable. It supports auto-negotiation of link speed and duplex mode. Ksz80 Ob S4lv0.2 Datasheet
Review based on probable KSZ80xx family (common features):
Assuming your device is a KSZ8081MNX/RNB or KSZ8091 (10/100 Mbps PHY):
1. Executive Summary
The part number "Ksz80 Ob S4lv0.2" appears to be a derivative of the Microchip KSZ80xx series of Single-Port 10/100 Ethernet Physical Layer Transceivers (PHYs). These devices are designed to interface standard MAC (Media Access Control) layers with twisted-pair copper media (RJ45). They are widely used in embedded systems, industrial automation, and consumer electronics due to their low power consumption and robust ESD protection. Because this is a proprietary component manufactured for
To a layman, it was a dry collection of pinout diagrams, thermal resistance tables, and timing characteristics for a specialized microprocessor. But to Elias, a freelance hardware forensicist, it was a roadmap to a ghost. The "S" in the revision stood for
PCB Number: KSZ80-0B-S4LV0.2 (also referred to as KSZ80_0B_S4LV0.2). Common Applications: Sony LED/LCD TVs (e.g., KDL-40R470A). Physical Layer: 10Base-T and 100Base-TX support
Device Compatibility: Specifically designed for Sony models like the KDL-40R473A and KDL-40R450A.
Compatibility: Strictly tied to specific panel models; replacing this board with a different version (even if it looks similar) can result in distorted images or no display. 3. Integrated Components (KSZ80 Series)
