Hello Gary,

Thanks for the advise, but I did realise that the input is x2 ie. 274
Khz, ...

based on the fact that you need the double frequency I assume that you want to drive a class-D PA push-pull amplifier. If that is the case there is no need to get a nice sine (through a LPF and bufferamplifier), most convenient is to pick up the 274kHz signal somewhere at TLL or CMOS level.
