Chip Overview: The KSZ8795CLXIC might refer to an Ethernet switch or similar network device. Ensure you have the correct documentation from the manufacturer, but based on typical naming conventions, here’s how the information could be structured.
Pin Function Table Example (assuming a 200-pin QFP package) Pin # Pin Name Function Description 1 VDD Power supply input for the core (typically 3.3V) 2 VSS Ground connection 3 RX0+ Ethernet receive signal (differential) 4 RX0- Ethernet receive signal (differential) 5 RX1+ Ethernet receive signal (differential) 6 RX1- Ethernet receive signal (differential) 7 TX0+ Ethernet transmit signal (differential) 8 TX0- Ethernet transmit signal (differential) … … … 200 RESET Reset signal inputThis table should include all 200 pins with corresponding descriptions. If there are multiple functions assigned to the same pin under different conditions (e.g., default vs. alternate), each should be listed with a detailed explanation of what happens under each mode.
2. Circuit Principles and Explanation
Power Supply: Pin 1 (VDD) is connected to the core power, typically 3.3V. VSS (Pin 2) provides the ground reference for the chip's internal circuitry. Ethernet Ports: The differential signals (e.g., RX0+/RX0-) form the backbone of the network communication and must be routed correctly to ensure stable data transmission. Reset Pins: A reset input on Pin 200 ensures the device can be reset under conditions where it is not functioning correctly, either via an external signal or during initialization. Clock Inputs: Often chips like the KSZ8795CLXIC will have an external clock input pin for synchronizing the internal circuitry. This might be one of the pins in the range of the first 10.3. 20 Common FAQ Questions with Answers

Pin #1 (VDD) is the power supply input, and Pin #2 (VSS) is the ground pin, which provides the reference voltage for the chip’s operation.3. How are the Ethernet signals transmitted on the KSZ8795CLXIC?
Ethernet signals are transmitted using differential pairs like RX0+/RX0-, TX0+/TX0-, ensuring stable communication across network cables.4. What is the reset pin function on the KSZ8795CLXIC?
Pin #200 (RESET) is used for resetting the chip, either manually or automatically, to initialize or recover from an error condition.5. Can the KSZ8795CLXIC operate in a high-speed mode?
Yes, the chip supports high-speed Ethernet operation through its differential signal pins for both reception and transmission.6. What are the voltage tolerances for the power supply pins?
Typically, the power supply voltage range is from 3.0V to 3.6V; however, please refer to the specific datasheet for precise tolerances.7. What is the maximum current that can be drawn from the VDD pin?
The exact current limit would be specified in the datasheet, but you can generally expect a current draw in the range of 100-200mA depending on the configuration.8. Does the KSZ8795CLXIC require external clock signals?
Yes, it likely requires an external clock signal for synchronization, typically input through specific clock pins.9. What are the common use cases for the KSZ8795CLXIC?
