MAX2880 EVALUATION KIT AVAILABLE 250MHz to 12.4GHz, High-Performance, Fractional/Integer-N PLL General Description 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-frequency and lownoise-phase frequency detector (PFD), precision charge pump, 10-bit programmable reference counter, 16-bit integer N counter, and 12-bit variable modulus fractional modulator.
