Part Number: SN65DSI86

Hi, Support team

The below is the current specification of SN65DSI186.

Was the above suspend current measured when the PWM is active?

If YES, how much is the suspend current if PWM is inactive?

And also, can you create the function block vs power state as follows?

	Normal	Suspend	Shutdown
DSI Packet Processor
Adaptive Display
eDP Main Link
AUX Channel
Clock Circuit
CSR

Thanks

suspend current measured when the PWM is off. will get those table information later.

Unfortunately, we do not have the data to create the functional block for each power state.

Thanks

Hi, David

The clock source is selected from one of two sources (REFCLK pin or DACP/N pins). Is the suspend current depending on the clock source? If YES, please inform me about suspend current when each clock source is selected.

Thanks

Please refer to Figure 3 of the DSI86 datasheet, the clock is off during SUSPEND.

Thanks
David
