Overview
MAX2870 is an ultra-wideband phase-locked loop (PLL), integrated voltage-controlled oscillator (VCO), and can work in integer and fractional-N modes. With an external reference clock oscillator and loop filter, the MAX2870 can form a high-performance frequency synthesizer to generate a clock in the frequency range of 23.5MHz to 6.0GHz, and can maintain excellent phase noise and spurious indicators. The internal multiple integrated VCO covering the 3000MHz to 6000MHz range and the 1-128 output divider are used to realize the clock output in an ultra-wide frequency range. The device provides dual-channel differential output drivers, which can be individually set to provide output power from -4dBm to +5dBm, and both outputs can be muted by software or hardware control.
MAX2870 is controlled by a 3-wire serial port and is compatible with 1.8V control logic. The device is packaged in a lead-free, RoHS-compliant 5mm x 5mm, 32-pin TQFN package and operates over an extended temperature range of -40C to +85C.
