MAX9517EVKIT+

19-0783; Rev 0; 3/07 MAX9517/MAX9524 Evaluation Kits The MAX9517/MAX9524 evaluation kits (EV kits) are fully assembled and tested surface-mount PCBs that evaluate the MAX9517 and the MAX9524 ICs. Both ICs filter, amplify, and set the sync-tip level for standarddefinition video signals. The ICs feature an internal reconstruction filter that has 40dB attenuation at 27MHz, and ±1dB passband flatness at 7MHz. The MAX9517 and MAX9524 have a 2V/V gain and are capable of driving 75Ω to ground. The ICs feature two analog switches that are used to route audio, video, or digital signals. Video signals are DC-coupled to the input of the MAX9517 and AC-coupled to the input of the MAX9524. The MAX9524 features an input sync-tip clamp to set the DC level for the video signal. The EV kits’ input terminal has 75Ω termination to ground. The EV kits’ output has a 75Ω back-termination resistor. The EV kits operate from a single 2.7V to 3.6V power supply.

Quick Start Recommended Equipment • 2.7V to 3.6V, 500mA DC power supply (VDD) • Video signal generator • Video measurement equipment (e.g., Tektronix VM700T) Procedure Each EV kit is a fully assembled and tested surfacemount PCB. Follow the steps below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. 1) Verify that a shunt is installed across pins 1-2 of jumper JU1 (EV Kit ON). 2) Connect the power-supply ground to the GND pad on the EV kit. 3) Connect the 2.7V to 3.6V power supply to the VDD pad on the EV kit. 4) Connect the output of the video signal generator to the IN BNC connector on the EV kit. Note: For the MAX9517, the video signal must be biased such that the sync tip is at ground. 5) Connect the OUT BNC connector on the EV kit to the input of the video measurement equipment. 6) Set the video signal generator for the desired video input signal, such as multiburst sweep. This signal must contain sync information. 7) Turn on the power supply and enable the video signal generator. 8) Analyze the video output signal with the VM-700T video measurement equipment. 2 Detailed Description Each EV kit is a fully assembled and tested PCB that contains all the components necessary to evaluate the performance of the MAX9517 or the MAX9524. Both ICs filter and amplify standard-definition video signals. The MAX9517/MAX9524 ICs feature an internal reconstruction filter that has 40dB attenuation at 27MHz and ±1dB passband flatness at 7MHz. The MAX9517 and MAX9524 have 2V/V gain and are capable of driving a 75Ω load to ground. Both ICs include two analog switches that can be used to route audio, video, or digital signals. The MAX9517 EV kit can be modified to evaluate the MAX9524 by installing capacitor C3, removing resistor R3, and replacing U1. See the EV-Kit Specific Component List for component values. Similarly, the MAX9524 EV kit can be modified to evaluate the MAX9517 by removing capacitor C3, installing resistor R3, and replacing U1. See the EV-Kit Specific Component List for component values. Jumper Selection Shutdown Mode (SHDN) Jumper JU1 controls the shutdown mode (SHDN) of the MAX9517 or MAX9524 ICs. The shutdown mode reduces the IC’s quiescent current. See Table 1 for shunt positions. Table 1.
