Dual Low-power Frequency Synthesizer -

The UMA1005T is a low-power, high-performance dual Frequency Synthesizer fabricated in CMOS technology. Fractional-N division with selectable modulo 5 or 8 is implemented in the main synthesizer. The detectors and Charge Pumps are designated to achieve 10 to 5000 kHz channel spacing using fractional-N decreases the channel spacing by a factor 5 or 8. Together with an external standard 2, 3 or 4 ratio prescaler the main synthesizer CAN operate in the GHz frequency range. Channel selection and programming is realized by a high-speed 3-wire serial Interface By NXP Semiconductors
