APPLICATIONS - 900 MHz cordless telephones - Portable battery-powered radio equipment. GENERAL DESCRIPTION UMA1016x T The UMA1016x T is a low power synthesizer for radio munications. Manufactured in bipolar technology, it is designed for a 70 to 1000 k Hz 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 parator. A power-down mode enables the circuit to be idled.
