Product Description
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 30 MHz to 6000 MHz. 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.
