2 / 17 page October 1992 2 Philips Semiconductors Product specification Low-power frequency synthesizer for mobile radio communications UMA1014 FEATURES • Single chip synthesizer; compatible with Philips cellular radio chipset • Fully programmable RF divider • I2C interface for two-line serial bus • On-chip crystal oscillator/TCXO buffer from 3 to 16 MHz • 16 reference division ratios allowing 5 to 100 kHz channel spacing • 1/8 crystal frequency output • On-chip out-of-lock indication • Two extra VCO control outputs • Latched synthesizer alarm output • Status register including out-of-lock indication and power failure • Power-down mode. APPLICATIONS • Cellular mobile radio (NMT, AMPS, TACS) • Private mobile radio (PMR) • Cordless telephones. 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 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 enable a better compromise between fast switching and loop bandwidth. A power-down circuit enables the synthesizer to be set to idle mode. QUICK REFERENCE DATA ORDERING INFORMATION SYMBOL PARAMETER MIN. TYP. MAX.
