Hi,
Can anyone suggest me some algorithm for viterbi decoder which can work at 350 MHZ ?I need to implement in Stratix2 GX board.

The algorithms for Viterbui decoding of convolutional encoded signals (e.g. rate 1/2 and constraint length 7, which is a common choice) are "frequency agnostic". They don't care what frequency or data rate is in use not what the clocking rate of the decoder is.
I suspect that what you really mean is "can you suggest an IMPLEMENTATION of Viterbi decoding which can work with a Stratix2 GX board?".
Keep in mind that Viterbi decoding's complexity increases exponentially as the constraint length K increases. As such, you may well be better off settling for a lower constraint length to accommodate your particular board, or going with more modern decoders such as Trellis or using Turbo codes which perform far better than Viterbi algorithms anyway.
