Philips LPC UART & CAN baud rates with 1 XTAL

Hi all,

Anyone some advice or experience on calculating the Xtal freq for a
LPC22xx ARM7.

I just don't find a correct value to generate stnadard UART baudrates
(9600, 19200, 38400..) and standard CAN-bus speeds (125,250,500,1000)

At this moment i have a 17.456MHz Xtal and this is working fine for the
UART.

For the CAN-bus, a multiple of 8Mhz should work fine.

I tried to get to a compromis by changing PLL and Peripheral clock
speeds, but it seems that there is no value that would exactly meet
both requirments.

Any suggestions on how to find the right frequency ?

Thanks

Stan
