3.1.1.3 Output Enable Pin

GUID-20230428-SS0I-4NKZ-BV1K-9RNB9SPHFDXT-low.pngFigure 3-4 LMK3H0102 Wizard Output Enable Pin Page

The Output Enable Pin page allows for configuration of the OE pin behavior. By default, the pin is configured as an active-low pin. The pin can be configured to active-high, where connecting the OE pin to GND disables the outputs.

The disabled state behavior can be set such that, on disable, the device enters a power-down mode with only I2C accessible. This is not recommended for applications where the clocks need to re-enable quickly, such as PCIe applications, as the device must power up again prior to the output clocks being ready.
