Product specification
UMA1016xT
FEATURES
• RF input frequencies to 1 GHz
• Fully programmable RF divider
• 3-wire serial bus interface
• On-chip 3 to 16 MHz crystal oscillator
• Mask programmable ÷2 to ÷31 reference divider ratio
• Up to 1 MHz channel spacing
• Crystal frequency buffered output
• Dual register architecture for fast Tx/Rx switching in
TDD single synthesizer systems
• Phase detector compensated for supply and
temperature variations
• Power-down mode.
GENERAL DESCRIPTION
The UMA1016xT is a low power synthesizer for radio
communications. Manufactured in bipolar technology, it is
designed for a 70 to 1000 kHz channel spacing in the
500 to 1000 MHz band. The channel is programmed via a
3-wire serial bus. The internal dual register architecture
allows a single synthesizer to be used in TDD systems.
Fast switching between transmit and receive frequencies
is achieved without the need for bus overhead. It also
incorporates a sensitive, low power RF divider and a
dead-zone-eliminated 3-state phase comparator.
A power-down mode enables the circuit to be idled.
APPLICATIONS
• 900 MHz cordless telephones
• Portable battery-powered radio equipment.
