Product Description
The RFFC5071A and RFFC5072A are re-configurable 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 VCO features temperature com-
pensation circuits that deliver stable performance across the operating tempera-
ture 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
4200MHz. The LO signal is buffered and routed to the integrated RF mixers which
are used to up/down-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 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 inter-
nal signals (the LOCK signal, for example) or to control front end components. Both
devices operate with a 2.7V to 3.3V power supply.
