Evaluate: MAX9507 19-0819 Rev 0 5/07 MAX9507 Evaluation Kit/Evaluation System General Description Features The MAX9507 evaluation kit (EV kit) is a fully assembled Single 1.7V to 2.625V Power-Supply Operation and tested surface-mount printed-circuit board (PCB) Video Load Detection TM that evaluates the MAX9507 DirectDrive video filter DC-Coupled Input with Option for AC-Coupling amplifier. The MAX9507 amplifies standard-definition DC-Coupled Output video signals and sets the video black level near ground while consuming minimal power. The EV kit Video Output Black Level Set Near Ground operates from a 1.7V to 2.625V single power supply Selectable Reconstruction Filter with 1dB and accepts an input video signal of up to 1V . The P-P Passband to 7.3MHz and 48dB Attenuation at 27MHz 2 EV kit includes an I C/SMBus-compatible interface, Internal Fixed Gain of 8V/V which provides software control of the video filter, ana- Dual SPST Analog Switches log switches, load detection, and other functions. 2 I C/SMBus-Compatible Interface The MAX9507 evaluation system (EV system) consists of Fully Assembled and Tested the MAX9507 EV kit and the Maxim CMAXQUSB+ com- mand module. A Windows 98/2000/XP-compatible software program is also available for use with the EV Ordering Information system and can be downloaded from Maxims website TEMP IC COMMAND (www.maxim-ic.com/evkitsoftware).
