Pin Configuration
I appreciate your request, but I must be transparent: no datasheet section has been provided in your message. The section header "3.0 PIN DESCRIPTIONS AND CONFIGURATION" is present, but the actual pin table content that would follow it is missing.
To extract an accurate pinout for the LAN9252 (64-pin QFN), I need:
- The pin description table(s) from the datasheet
- Pin numbers, names, types (I/O, power, ground, etc.)
- Functional descriptions for each pin
Please provide the complete pin descriptions section from the LAN9252 datasheet, and I will extract a clean, structured pinout table immediately.

Note 1: When powering this device from laboratory or system power supplies, it is important that the absolute maximum ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output. If this possibility exists, it is suggested to use a clamp circuit.
-
Note 2: This rating does not apply to the following pins: OSCI, RBIAS
-
Note 3: This rating does not apply to the following pins: RBIAS
*Stresses exceeding those listed in this section could cause permanent damage to the device. This is a stress rating only. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Functional operation of the device at any condition exceeding those indicated in Section 18.2, "Operating Conditions\\", Section 18.5, "DC Specifications", or any other applicable section of this specification is not implied. Note, device signals are NOT 5 volt tolerant.
