Features: The MAX2870 is awide band phase-locked loop (PLL) with integrated voltage controlled oscillators (VCOs) capable of operating in both integer-N and fractional-N modes. When coupled with an externals reference oscillator and loop filter, the MAX2870 constitutes a high working performance frequency synthesizer capable of synthesizing frequencies from 23.5MHz to 6000MHz while maintaining superior phase noise and spurious performance. Built-in multiple integrated VCOs covering(ranges from 3000MHz to 6000MHz) and output dividers(ranging from 1 to 128) which is used to implement clock output overing a wide frequency ranges. Compatible with 1.8V control logic. The onboard with default high precise 25MHz 0.5ppm TCXO, the internal VCO base frequency output frequency is ranging from 3-6GHz, below 3GHz is the base frequency division. It can be controlled by PC, output amplitude: -4 to 5dBm, 4-level screen controls. Equipped with two frequency output modes, you can choose dot frequency and sweepingfrequency according to your demands. Main Features: Integer and fractional-N frequency division modes. Support manual or automatic VCO selection. 3000MHz to 6000MHz fundamental VCO. Output binary buffers/dividers for extended frequency ranges: 1/2/4/8/16/32/64/128; 23.5MHz to 6000MHz. Fine performance PFD: 105MHz in integer-N mode; 50MHz in fractional-N mode. Reference frequency up to 200MHz. Operates from +3.0V to +3.60V supplys. Dual programmable outputs: -4dBm to +5dBm. Hardware and software shutdown controls. Compatible with 1.8V controls logic. Applications: Clock Generation PMAR/LMAR/Public Safety Radio Test and Measurement Module Features: Module power supply TYPE-C: 5V@0.2A. Output and external clock interface: SMA-K (inner screw inner hole). The onboard default high-precision 25MHz 0.5ppm TCXO (can also be replaced or connected to an external clock). Output frequency range: the fundamental frequency of the internal VCO is 3-6GHz, and the frequency below 3GHz is obtained from the fundamental frequency division. Output amplitude: -4 to 5dBm, 4 levels ofscreen control. Output frequency mode: point frequency, sweepingfrequency optional screen control. Provide PC upper computer control program.
