INTEGRATED CIRCUITS DATA SHEET UMA1016x T Frequency synthesizer for radio munication equipment Product specification Supersedes data of June 1992 File under Integrated Circuits, IC03 1995 Jul 12 Philips Semiconductors Product specification Frequency synthesizer for radio munication equipment 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 pensated for supply and temperature variations - Power-down mode. 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.
