UMA1005 Description
GENERAL DESCRIPTION UMA1005T 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.
