250MHz to 12.4GHz, High-Performance, Fractional/Integer-N PLL

High-Frequency PLL Breaks New Performance Barriers

Please check latest availability status for a specific part variant.


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 ultra-low 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 low-noise-phase frequency detector (PFD), precision charge pump, 10-bit programmable reference counter, 16-bit integer N counter, and 12-bit variable modulus fractional modulator.

The MAX2880 is controlled by a 3-wire serial interface and is compatible with 1.8V control logic. The device is available in a lead-free, RoHS-compliant, 20-pin TQFN package, and operates over an extended -40°C to +85°C temperature range.
