UMA1014 Product details

Description

UMA1014 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 I2C-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

Features
