Overview
The MAX2871ETJ+T is a high-performance frequency synthesizer produced by Analog Devices Inc./Maxim Integrated. This ultra-wideband phase-locked loop (PLL) integrates voltage control oscillators (VCOs) and is capable of operating in both integer-N and fractional-N modes. It synthesizes frequencies from 23.5MHz to 6.0GHz, maintaining superior phase noise and spurious performance. The device is particularly useful in applications requiring a wide frequency range and high precision.
