The MAX2880 is a phase-locked loop (PLL) that operates in both integer-N and fractional-N modes. This ultra-low noise and low-spur frequency synthesizer is capable of synthesizing frequencies from 250 MHz to 12.4 GHz when combined with an external reference oscillator, loop filter, and VCO. It has integrated 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 1.8 V control logic. It is available in a lead-free, RoHS-compliant, 20-pin TQFN and 16-pin TSSOP packages and is ideal for clock generation, wireless infrastructure, satellite communications, test and measurement applications.
