Part Number: LSF0108

Hi team,

Could you pls help to review the LSF0108 schematic? It is for the 30MHz SPI application,1.2V to 1.8V.

An connect to FPGA without pull-up resistor and Vref_A=1.2V;

Bn pull-up to 1.8V with 100ohm and Vref_B=3.3V.

I have checked the schematic following the design procedure on the datasheet and the schematic looks good to me.

Really appreciate it if you could double check the schematic.

Thanks!

Hey Reagan,

This schematic looks fine. I would just make sure you have pull-up resistors where they are needed (e.g. they will be needed if the signal is being up translated). You can find more details in these training videos on the LSF family (specifically 4, 5, and 6).
