RF Signal Generator MAX2870 23.5MHz-6GHz Phase-Locked Loop RF Source

Description:
The MAX2870 is an ultra-wideband phase-locked loop (PLL) with an integrated voltage-controlled oscillator (VCO) that operates in both integer and fractional-N mode. Combined with an external reference clock oscillator and loop filter, the MAX2870 forms a high-performance frequency synthesizer that produces clocks in the 23.5MHz to 6.0GHz frequency range and maintains excellent phase noise and spurs. Multiple integrated VCOs ranging from 3000MHz to 6000MHz and 1-128 output dividers are used to achieve clock output over an ultra-wide frequency range. The device provides a dual differential output driver that can be individually set to provide -4dBm to +5dBm output power, both outputs can be muted by software or hardware control.

The MAX2870 is controlled by a 3-wire serial port and is compatible with 1.8V control logic. The device is available in a lead-free, RoHS-compliant, 5mm x 5mm, 32-pin TQFN package and operates in the range of -40°C to +85°C.
