MAX2880 - Maxim Integrated

MAX2880 Fractional/Integer-N PLL

The MAX2880 is a high-performance phase-locked loop (PLL) capable of operating in both integer-N and fractional-N modes. Combined with an external reference oscillator, loop filter, and VCO, the device forms an ultralow noise and low-spur frequency synthesizer capable of accepting RF input frequencies of up to 12.4GHz. The MAX2880 consists of a high-frequenc.
