SN65DSI84: what is the actual maximum current draw?

Eric Steimle

Part Number: SN65DSI84

The datasheet lists the max current for the SN65DSI84 as 1.8V @ 150mA however it has a bunch of caveats about that in the notes section. So since I have to come up with a real power budget for this part can you tell me what the real worst case current draw would be?

Thank you

Could you please provide details on your implementation?

Single Channel DSI Input --> Dual Channel LVDS Outputs
Panel Resolution
Number of DSI Lanes
LVDS Output Clock Frequency
DSI Input Clock Frequency
Mode = 18 BPP or 24BPP

Sure it's:

4 Channel DSI Input --> Single Channel LVDS Outputs (4 lvds lanes + 1 clk)
Panel Resolution 1360x768 @60hz
Number of DSI Lanes: 4
LVDS Output Clock Frequency: is this just the pixel clock? It's hard to tell from the datasheet if so 63Mhz
DSI Input Clock Frequency 188Mhz
Mode = 24BPP

Hello Eric,

The worst case current draw for the above conditions would be 120mA.
