Hello

In my new project I want to connect the SN55LVDS31( Differential Line Drivers) to sn55lvds32 (Differential Line Reciever) that locate on my other PCB .

The SN55LVDS31 is adapted to work with sn55lvds32?

Both conform to the LVDS specification, so they are compatible.

Hi Roi,

Yes both of these devices are driver/receiver pair. As Clemens points out, any driver/ receiver pair can be combined if they are both compliant to the LVDS standard.

Thanks, Amy

Thanks.

What is the power consumption?

Icc X Vcc = 35mA * 3.3V = 115mW?

Correct.

Some of the load current flows through the bus and the termination resistors, so not all of this is dissipated inside the chip. But the estimated dissipation in the resistors for all channels is 4 × 3.5 mA × (3.5 mA × 100 Ω) ≈ 5 mW.
