ADF4212BRUZ-RL7

Clock Generator 0MHz to 2.7GHz Input 20Pin TSSOP T/R

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.
