MAX2870

EVALUATION KIT AVAILABLE MAX2870 23.5MHz to 6000MHz Fractional/ Integer-N Synthesizer/VCO General Description The MAX2870 is an ultra-wideband phase-locked loop (PLL) with integrated voltage control oscillators (VCOs) capable of operating in both integer-N and fractional-N modes. When combined with an external reference oscillator and loop filter, the MAX2870 is a high-performance frequency synthesizer capable of synthesizing frequencies from 23.5MHz to 6.0GHz while maintaining superior phase noise and spurious performance. The ultra-wide frequency range is achieved with the help of multiple integrated VCOs covering 3000MHz to 6000MHz, and output dividers ranging from 1 to 128. The device also provides dual differential output drivers, which can be independently programmable to deliver -4dBm to +5dBm output power. Both outputs can be muted by either software or hardware control. The MAX2870 is controlled by a 3-wire serial interface and is compatible with 1.8V control logic. The de...
