    • Methods and systems for coexistence in a multiband, multistandard communication system utilizing a plurality of phase locked loops (PLLs) are disclosed. Aspects may include determining one or more desired frequencies of operation of a transceiver, determining a frequency of unwanted signals such as spurs, intermodulation, and/or mixing product signals, and configuring the PLLs to operate at a multiple of the desired frequencies while avoiding the unwanted signals. The desired frequencies may be generated utilizing integer, which may include multi-modulus dividers. The wireless standards may include LTE, GSM, EDGE, GPS, Bluetooth, WiFi, and/or WCDMA, for example. The frequencies may be configured to mitigate interference. PLLs may be shared when operating in TDD mode, and used separately operating in FDD mode. One or more digital interface signals, zero exceptions on a transmitter spur emission mask, and sampling clocks for ADCs and/or DACs in the transceiver may be generated utilizing the PLLs.

    • Embodiments of this disclosure include methods in which spurs generated by the drifting of an oscillation frequency of an oscillation signal provided by a free-running oscillator may be minimized and/or eliminated from an output signal of a phase locked loop (PLL). Methods include adjusting the free-running oscillator to prevent the oscillation frequency from drifting so that the spurs are eliminated. Performance data generated when the communications device engages a communications channel that is known not to generate spurs is compared to performance data generated when the communications device engages a desired communications channel. The free-running oscillator is adjusted until the two types of performance data are matched. Other methods include adjusting the dithering module of the PLL to prevent the oscillation frequency from drifting so that the spurs are eliminated.
