Product Description
The RF2051 is a low power, high performance, wideband RF frequency conversion
chip with integrated local oscillator (LO) generation and a pair of RF mixers. The RF
synthesizer includes an integrated fractional-N phase locked loop with voltage con-
trolled oscillators (VCOs) and dividers to produce a low-phase noise LO signal with a
very fine frequency resolution. The buffered LO output drives the built-in RF mixers
which convert the signal into the required frequency band. The mixer bias current
can be programmed dependent on the required performance and available supply
current. The LO generation blocks have been designed to continuously cover the
frequency range from 300MHz to 2400MHz. The RF mixers are very broad band
and operate from 30MHz to 2500MHz at the input and output, enabling both up
and down conversion. An external crystal of between 10MHz and 52MHz or an
external reference source of between 10MHz and 104MHz can be used with the
RF2051 to accommodate a variety of reference frequency options.
All on-chip registers are controlled through a simple three-wire serial interface. The
RF2051 is designed for 2.7V to 3.6V operation for compatibility with portable, bat-
tery powered devices. It is available in a plastic 32-pin, 5mmx5mm QFN package.
