TMDSCNCD28388D: DP83822IRHBR pin 24 on MCU063A doesn't match its function

Part Number: TMDSCNCD28388D

Hi,  I saw that the pin 24 of the DP83822IRHBR IC on the new schematic of the board MCU063A said CLK_O (i guess is clock output signal) but I don't see that specification on the IC datasheet. Attached is the pictures with the detail.

It's an error, or there is some version of the PHY that come with clk out?

May I use these pin as the datasheet specification ?

regards

Pablo

    Pablo,

    When creating the schematic representation of a device you can name the pins anything. The creator of this schematic symbol chose to call LED_1/GPIO1 "CLK_O". I assume because it indicates the clock rate of the link.

    None the less, you are looking at the correct schematic and datasheet, follow the DP83822's datasheet.
