Evaluates: MAX2880 MAX2880 Evaluation Kit General Description Features The MAX2880 evaluation kit (EV kit) facilitates the evaluation Easy Evaluation of the MAX2880 of the MAX2880 wide-band phase-locked loop (PLL). It is a All Critical Peripheral Components Included fully assembled and tested frequency synthesizer consist- PC-Based Control Software ing of the IC, 5840MHz to 6040MHz external VCO, 50MHz TCXO, passive-loop filter, and low-dropout regulators. Proven PCB Layout A software application, running on a PC with Windows Fully Assembled and Tested XP or later Windows operating system, simplifies the Quick Start control of the IC in various operating modes and features. Required Equipment EV Kit Contents +6.0V power supply, capable of delivering 150mA The EV kit package contains the following: USB cable, type A to type B EV kit board Windows PC Maxim INTF-3000-to-USB interface board Signal source analyzer or spectrum analyzer 20-pin ribbon cable for connecting EV kit to Power cables and an SMA-terminated, 50 RF cable INTF-3000 board The content of this document includes: Brief test procedure to verify functionality Ordering Information appears at end of data sheet.
