My paper "Polyphase Filter Matrix for Rational Sampling Rate Conversions" on Proc. of ICASSP '87, pp. 2173-2176 should help for this design need. The polyphase filter matrix downsamples first and then upsamples for the exacly same output. So the intermediate sampling rate is 300Hz instead of 7.056MHz. What a difference! - Chuck
