Usually GPS receivers have CPU clock frequencies that are not an integer multiple of the chipping rate: that's why there is the sawtooth correction in the timing units. The LO frequency for the receiver front-end is not a problem due to the fractional-N PLL. The Motorola M12 seems to use a 40MHz clock, uBlox receivers use 48MHz clock...
