Phase Locked Loop by Maxim Integrated

Note : Your request will be directed to Maxim Integrated.

The MAX2871 from Maxim Integrated is a phase-locked loop (PLL) with integrated voltage controlled oscillators (VCOs) that operates in both integer-N and fractional-N modes. It is capable of synthesizing frequencies from 23.5 MHz to 6.0 GHz while maintaining superior phase noise and spurious performance, when combined with an external reference oscillator and loop filter. This ultra-wide frequency range is achieved with the help of multiple integrated VCOs covering 3000 MHz to 6000 MHz, and output dividers ranging from 1 to 128.

It provides dual differential output drivers, which can be independently programmable to deliver -1 dBm to +8 dBm output power. Both outputs can be muted by either software or hardware control. The device is controlled by a 4-wire serial interface and is compatible with 1.8 V control logic. It is available in a lead-free, RoHS-compliant, 5 x 5 mm, 32-pin TQFN package and is ideal for clock generation, wireless infrastructure, microwave radios, test and measurement applications.
