UMA1015AM Low-power Dual Frequency Synthesizer For Radio Communications

The UMA1015AM is a low-power dual Frequency Synthesizer for Radio Communications which operates in the 50 to 1100 MHz frequency range. Each synthesizer consists of a fully programmable main divider, a phase and frequency detector and a Charge Pump There is a fully programmable reference divider common to both synthesizers which operates up to 35 MHz. The device is programmed via a 3-wire serial bus which operates up to 10 MHz. The Charge Pump currents (gains) are fixed by an external resistance at pin 20 (ISET). The BiCMOS device is designed to operate from 2.7 V (3 NiCd cells) to 5.5 V at low current. Digital supplies VDD1 and VDD2 must be at the same potential. The Charge Pump supply (VCC) CAN be provided by an external source or on-chip voltage doubler. VCC must be equal to or higher than VDD1. Each synthesizer CAN be powered-down independently via the serial bus to save current. It is also possible to power-down the device via the HPD input (pin 5).
