MCD2926

MCD2926 18MHz-650MHz Dual Frequency Synthesizer (Version 2.5) MC Devices® MCD2926 18MHz-650MHz Dual Frequency Synthesizer General Description The MCD2926 is a high performance dual frequency synthesizer with high frequency prescaler for RF operation frequency from 18MHz to 650MHz. The MCD2926 contains two dual modulus prescalers, three programmable counters, one crystal oscillator, two phase detectors and two programmable charge pumps, one MCU serial interface. The on-chip prescalers and dividers consist of a completed phase-lock-loop (PLL), which is combined with on board VCO and LPF. Users can lock any targeted frequency by setting proper division with an external MCU. It has been proven that MCD2926 can work stably within the range of -40 to +85 degrees. Typical Applications ■ FRS, PCS, Cordless phones ■ Portable wireless systems and other wireless ■ communication systems Features ■ Operating Frequency: 18MHz~650MHz ■ Operating Voltage Range: 2.2 ~ 5.5V (3.3V Typical) ...
