RFFC5071/5072

WIDEBAND SYNTHESIZER/VCO WITH

INTEGRATED 6GHz MIXER

The RFFC5071 and RFFC5072 are reconfigurable frequency conversion devices

with integrated fractional-N phased locked loop (PLL) synthesizer, voltage con-

trolled oscillator (VCO) and either one or two high linearity mixers. The fractional-N

synthesizer takes advantage of an advanced sigma-delta modulator that delivers

ultra-fine step sizes and low spurious products. The PLL/VCO engine combined with

an external loop filter allows the user to generate local oscillator (LO) signals from

85MHz to 4200MHz. The LO signal is buffered and routed to the integrated RF mix-

ers which are used to convert frequencies ranging from 30MHz to 6000MHz. The

mixer bias current is programmable and can be reduced for applications requiring

lower power consumption.

Both devices can be configured to work as signal sources by bypassing the inte-

grated mixers. Device programming is achieved via a simple 3-wire serial interface.

In addition, a unique programming mode allows up to four devices to be controlled

from a common serial bus. This eliminates the need for separate chip-select control

lines between each device and the host controller. Up to six general purpose out-

puts are provided, which can be used to access internal signals (e.g. the LOCK sig-

nal) or to control front end components. Both devices operate with a 2.7V to 3.3V

power supply.
