Abstract
A receiver for OFDM subcarriers has a first mode and a second mode. In the first mode, a tunable system clock is output at a nominal frequency, and in the second mode, the tunable system clock is offset so that a harmonic of the tunable system clock coincides with a particular OFDM subcarrier. The tunable system clock is coupled to a programmable modem PLL clock generator which generates clocks for an A/D converter coupled to a baseband processor which is also coupled to the programmable modem PLL clock generator. The programmable modem PLL clock generator is programmed to maintain a constant output frequency of each output in the first mode and the second mode.
