The TRF2056 device is a low-voltage, low-power consumption 1.2-GHz fractional-N/integer-N frequency synthesizer component for wireless applications. Fractional-N division and an integral speed-up charge pump achieve rapid channel switching. Two operating modes are available: 1) SA7025 emulation mode in which the device emulates the Philips SA7025 fractional-N synthesizer and 2) extended performance mode (EPM), which provides additional features, including fractional accumulator modulos from 1 to 16 (compared to only 5 or 8 for the SA7025 synthesizer).
