Overview
The MAX2870ETJ+G2Z is an ultra-wideband phase-locked loop (PLL) synthesizer produced by Analog Devices Inc./Maxim Integrated. This device is designed to operate in both integer-N and fractional-N modes, making it highly versatile for a wide range of frequency synthesis applications. It integrates multiple voltage-controlled oscillators (VCOs) and output dividers, enabling the synthesis of frequencies from 23.5MHz to 6.0GHz. The MAX2870ETJ+G2Z is packaged in a 32-pin TQFN (5mm x 5mm) lead-free, RoHS-compliant package and operates over an extended temperature range of -40°C to +85°C.
