RF2052 HIGH PERFORMANCE WIDEBAND RF PLL/VCO WITH INTEGRATED RF MIXER Package: QFN, 32-Pin, 5mmx5mm VCO Features LO divider 30MHz to 2.5GHz Frequency Range Fractional-N Synthesizer Synth Frac-N Mixer Very Fine Frequency Resolution sequence N divider 1.5Hz for 26MHz Reference generator Low Phase Noise VCO Phase / Charge freq On-Chip Crystal-Sustaining pump detector Circuit With Programmable Loading Capacitors Ref High-Linearity RF Mixer divider Integrated LO Buffer Functional Block Diagram Mixer Input IP3 +18dBm Mixer Bias Adjustable for Low Product Description Power Operation The RF2052 is a low power, high performance, wideband RF frequency conversion 2.7V to 3.6V Power Supply chip with integrated local oscillator (LO) generation and RF mixer. The RF synthe- Low Current Consumption sizer includes an integrated fractional-N phase locked loop with voltage controlled 55mA to 75mA at 3V 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 mixer which 3-Wire Serial Interface converts the signal into the required frequency band. The mixer bias current can be programmed dependent on the required performance and available supply current. Applications The LO generation blocks have been designed to continuously cover the frequency CATV Head-Ends 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 con- Digital TV Up/Down Converters version. An external crystal of between 10MHz and 52MHz or an external reference Digital TV Repeaters source of between 10MHz and 104MHz can be used with the RF2052 to accom- Multi-Dwelling Units modate a variety of reference frequency options. Cellular Repeaters All on-chip registers are controlled through a simple three-wire serial interface. The RF2052 is designed for 2.7V to 3.6V operation for compatibility with portable, bat- Frequency Band Shifters tery powered devices. It is available in a plastic 32-pin, 5mmx5mm QFN package.
