TS3DDR3812: Is TS3DDR3812 suitable for DSI and LVDS application

LEI YAN

Part Number: TS3DDR3812
Other Parts Discussed in Thread: TS5MP645,

Hello e2e,

Since the TS5MP645 need special PCB process, the customer want to use TS3DDR3812 in both DSI and LVDS application, is it ok to use it?

Thanks in advance.

Hey Leon,

Is the problem the BGA package or the multilayer and vias recommended for the routing?
What voltage and frequency ranges would their LVDS and DSI signal that would go through the TS3DDR3812 have? If your voltage and frequency lie within the recommended specifications of the device you should be fine to use it.

Thanks,
Rami

Hello Rami,

Yes, the vias need blind via and buried via, it's high in cost.

the LVDS and DSI they used is 1.8V, it seems there is no resitricion in datasheet on that, can you help to have a check?

thank you.

LEON,

If the signals are only going from 1.8V to 0V than this should be fine. As you highlighted the multiplexer can only pass through signals from 0 to Vcc and the supply voltage should be 3.3-3.6V

Thanks,
Rami
