ADF4213:  Dual RF/IF PLL Frequency Synthesizer 1.0 GHz / 3 GHz

Product Details


The ADF4210/ADF4211/ADF4212/ADF4213 is a dual frequency synthesizer which can be used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. They can provide the LO for both the RF and IF sections. They consist of a low-noise digital PFD (Phase Frequency Detector), a precision charge pump, a programmable reference divider, programmable A and B counters and a dual-modulus prescaler (P/P+1). The A (6-bit) and B (12-bit) counters, in conjunction with the dual modulus prescaler (P/P+1), implement an N divider (N=BP+A). In addition, the 15-bit reference counter (R Counter), allows selectable REFIN frequencies at the PFD input. A complete PLL (Phase-Locked Loop) can be implemented if the synthesizers are used with an external loop filter and VCO's (Voltage Controlled Oscillators)Control of all the on-chip registers is via a simple 3-wire interface. The devices operate with a 3V ( ± 10%) or 5V( ± 10%) power supply and can be powered down when not in use.

Fundamentals of Frequency Synthesis, Part 1: Phased Locked Loops
The first of a two-part series on frequency synthesis, with an introduction to Phased Locked Loops. This webcast looks at the need for frequency generation, the techniques from the past present and future, and how to assess the performance of a frequency synthesis, and real world applications. Particular attention will be focused on Phase Locked Loops (PLL's) as frequency synthesizers.

Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
This month we conclude our two-part series on frequency synthesis, with an introduction to Direct Digital Synthesis. We will give a basic review of how a direct digital synthesis system works, touching on the inner workings of the DDS engine at a relatively high level. We will also discuss the tradeoffs between PLL and DDS technology as a base choice for frequency synthesis needs.
