Quick Start The MAX2754 EV kit is fully assembled and factory tested. Follow the instructions in the Connections and Setup section for proper device evaluation. Test Equipment Required This section lists the recommended test equipment to verify operation of the MAX2754. It is intended as a guide only, and some substitutions are possible. Connections and Setup This section provides a step-by-step guide to the functions and operation of these EV kits. 1) Connect a DC supply set to +3V (through an ammeter, if desired) to the VCC and GND terminals on the EV kit. 2) Apply +3V to the SHDN control input. 3) Turn on the DC supply. The supply current should read about 13.5mA. 4) Connect the VCO output to a spectrum analyzer with a 50Ω coaxial cable (minimize length). 5) Apply a variable DC voltage to the TUNE input (+0.4V to +2.4V). 6) Check fMIN and fMAX on the spectrum analyzer by varying the tuning voltage. 7) Apply a variable DC voltage to the MOD input (+0.4V to +2.4V). 8) Check modulation peak frequency deviation on the spectrum analyzer by varying the modulation voltage. 9) Check the output power level (-5dBm typ). ________________________________________________________________ Maxim Integrated Products For pricing, delivery, and ordering information, please contact Maxim/Dallas Direct! at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com. 1 Evaluates: MAX2754 General Description The MAX2754 evaluation kit (EV kit) simplifies evaluation of the MAX2754 VCO. This kit enables testing of the device’s RF performance and requires no additional support circuitry. The signal output uses an SMA connector to facilitate the connection to RF test equipment.
