Hi team,

Could you describe the recommended schematic for VDD pin, OE0/1/2/3 pins, VAC_REF0 pin and VAC_REF1 pin?

It seem there are no any recommended schematics related to those pins in the datasheet.

Regards,

Takahashi-san,

Please reference page 5 of the LMK1D1208EVM User Guide (https://www.ti.com/lit/ug/snau259/snau259.pdf?ts=1759849456880&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FLMK1D1208EVM).

Thanks,

Michael

H Michael,

I think LMK1D1208 is little bit different with LMK1D1204P as below. How should they deal with OE0/1/2/3 pins and Vdd pins?

- LMK1D1208 doesn't have OE0/1/2/3 pins.

- LMK1D1208 has Vcc pins, while LMK1D1204P has Vdd pins.

Takahashi-san,

The OE pins should be pulled up to VDD (for the outputs that are to be enabled, otherwise, pull them low) and the VCC pins should be treated the exact same as the VDD pins on the LMK1D1208EVM.

Thanks,

Michael
