I am working on LPC1768, Interfaced with CS5463.

Getting Clock and MOSI pulses of 3.3V even making it open drain, As of my knowledge CS5463 needs Pulses having 4.8V for High Logic, Alias I am getting to 3.3V only That is why my SPI is malfunctioning, Readings are not stable and even not precised..

 

So how can i get upto 5V pulses from SPI pins.

 

Regards Nisarg.
