Product Description
The RFFC2071A and RFFC2072A are re-configurable frequency conversion devices
with integrated fractional-N phased locked loop (PLL) synthesizer, voltage controlled
oscillator (VCO) and either one or two high linearity mixers. The fractional-N synthe-
sizer takes advantage of an advanced sigma-delta modulator that delivers ultra-fine
step sizes and low spurious products. The VCO features temperature compensation
circuits that deliver stable performance across the operating temperature range of
-40°C to +85°C. The PLL/VCO engine combined with an external loop filter allows
the user to generate local oscillator (LO) signals from 85MHz to 2700MHz. The LO
signal is buffered and routed to the integrated RF mixers which are used to
up/down-convert frequencies ranging from 30MHz to 2700MHz. The mixer bias cur-
rent is programmable and can be reduced for applications requiring lower power
consumption. Both devices can be configured to work as signal sources by bypass-
ing the integrated 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 outputs are provided, which can be used to access internal signals (the
LOCK signal, for example) or to control front end components. Both devices operate
with a 2.7V to 3.3V power supply.
