MAX2880 250MHz to 12.4GHz, High-Performance, Fractional/Integer-N PLL General Description Benefits and Features The MAX2880 is a high-performance phase-locked Integer and Fractional-N Modes loop (PLL) capable of operating in both integer-N and 250MHz to 12.4GHz Broadband RF Input fractional-N modes. Combined with an external reference Normalized In-Band Noise Floor oscillator, loop filter, and VCO, the device forms an ultra- -229dBc/Hz in Integer Mode low noise and low-spur frequency synthesizer capable of -227dBc/Hz in Fractional Mode accepting RF input frequencies of up to 12.4GHz. -10dBm to +5dBm Wide Input Sensitivity The MAX2880 consists of a high-frequency and low- Low-Noise Phase Frequency Detector noise-phase frequency detector (PFD), precision charge 125MHz in Fractional Mode pump, 10-bit programmable reference counter, 16-bit 140MHz in Integer Mode integer N counter, and 12-bit variable modulus fractional modulator. Reference Frequency Up to 210MHz The MAX2880 is controlled by a 3-wire serial interface Operates from +2.8V to +3.6V Supply and is compatible with 1.8V control logic. The device is Cycle Slip Reduction and Fast Lock available in a lead-free, RoHS-compliant, 20-pin TQFN Software and Hardware Shutdown package, and operates over an extended -40C to +85C Software Lock Detect temperature range.
