Preliminary

Product Description

The RF2053 is a very wideband RF frequency conversion chip with integrated local

oscillator (LO) generation and an RF mixer. The RF synthesizer includes an inte-

grated fractional-N phase locked loop that can control an external VCO to produce a

low-phase noise LO signal with a very fine frequency resolution. The LO output

drives the built-in RF mixer which converts the signal into the required frequency

band. The bias current can be programmed to optimize the supply current/perfor-

mance trade-off. The LO generation blocks have been designed to continuously

cover the frequency range from 300MHz to 2400MHz. The RF mixer is very broad

band and operates from 100MHz to 2500MHz at the RF ports of the device. 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.

The device is programmed using a true three-wire serial interface. The RF2053 is

designed for 2.7V to 3.6V operation for compatibility with portable, battery pow-

ered devices. It is available in a plastic 32-pin, 5mmx5mm QFN package.
