Product Description
The RF2053 is a low power, high performance, wideband RF frequency conversion
chip with integrated local oscillator (LO) generation and RF mixer. The RF synthe-
sizer includes an integrated fractional-N phase locked loop that can control an
external VCO to produce a low-phase noise LO signal with a very fine frequency res-
olution. The VCO output frequency can be divided by 1, 2, or 4 in the LO divider,
whose output is buffered and drives the built-in RF mixer which converts 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 gen-
eration blocks have been designed to operate with external VCOs covering the fre-
quency range from 300MHz to 2400MHz. The RF mixer is very broad band and
operates 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 RF2053 to
accommodate a variety of reference frequency options.
All on-chip registers are controlled through a simple three-wire serial interface. The
RF2053 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.
