GENERAL DESCRIPTION
The UMA1014 is a low-power universal synthesizer which
has been designed for use in channelized radio
communication. The IC is manufactured in bipolar
technology and is designed to operate at 5 to 100 kHz
channel spacing with an RF input from 50 to 1100 MHz.
The channel is programmed via a standard I
2
C-bus. A
low-power sensitive RF divider is incorporated together
with a dead-zone eliminated, 3-state phase comparator.
The low-noise charge pump delivers 1 mA or 1/2 mA
output current to enable a better compromise between fast
switching and loop bandwidth. A power-down circuit
enables the synthesizer to be set to idle mode.
