LMH1228: Power-save and power-down mode control by SPI control

Takahiro Saito

Part Number: LMH1228

Hi team,

Looking at the datasheet page 17, LMH1228 goes to power-save mode when there is no input signal.

Regardless of with or without input signal, is there any way to make LMH1228 into power-save mode by SPI register control?

I found 0x60 register can control the operating mode either normal mode or power-down mode. But, I can't find the way to make LMH1228 into power save mode. So, I appreciate it if you could tell me the way for it.

Regards,

Saito

Hi Nasser-san,

This command is to enable power-down mode through register control, right?

Customer needs to know the way for enabling power-save mode through SPI register control.

If there is any way to enable power save mode through SPI register control, could you show me how to do that?

Regards,

Saito
