GENERAL DESCRIPTION
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.
