	You should be ok with any of the MAX32XX line of transcievers
but if this is your first time using one of these I would recomend
that you stay away from using the crarge pump versions you mentioned 
earlier. Instead maxim also has transcievers in that line that are using
capacative voltage doubblers. They produce much fewer noize problems on
the related circuit and will save you a lot of hastle if you are doing any
RF work near the Maxim chip. 

	Good luck.
