UMA1005 Product details

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 or 8. Together with an external standard 2, 3 or 4 ratio prescaler the main synthesizer can operate in the GHz frequency r

Features

Auxiliary synthesizer.
Digital phase comparator with proportional and integral charge pump output.
High-speed serial input.
Low-power consumption.
Programmable charge pump currents.
Supply voltage range 2.9 to 5.5 V.
