Evaluates: MAX11500 General Description Evaluates: MAX11500 MAX11500 Evaluation Kit Quick Start Recommended Equipment Before beginning, the following equipment is needed: * 5V, 200mA DC power supply (VCC) * Video signal generator (e.g., Tektronix TG-2000 or TG-700) * Video measurement equipment (e.g., Tektronix VM-6000 or equivalent) Procedure The MAX11500 EV kit is fully assembled and tested. Follow the steps below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. 1) Connect the video signal generator output to the VIDIN_ BNC connectors on the MAX11500 EV kit. 2) Connect the VIDOUT_ BNC connectors on the EV kit to the input of the video measurement equipment. 3) Connect the power-supply ground to the GND pad on the EV kit. 4) Connect the 5V supply to the VCC pad on the EV kit. 5) Verify that no shunts are installed across jumpers JU1, JU3, JU5, JU7, JU8, and JU9 (AC-coupled inputs and outputs), and JU2 (no DC bias at VIDIN1). 6) Install shunts across jumpers JU4 and JU6 (DC bias for VIDIN2 and VIDIN3). 7) Set the video signal generator for the desired video input signal using a YPBPR signal format. 8) Connect the Y signal to the VIDIN1 BNC connector, and PB and PR to VIDIN2 and VIDIN3, respectively. 9) Turn on the power supply and enable the video signal generator output. 10) Analyze the video output signal with the video measurement equipment. Detailed Description The MAX11500 EV kit is a fully assembled and tested surface-mount PCB that contains a MAX11500 IC. The MAX11500 is a 3-channel video filter for reconstruction and anti-aliasing applications. All 3 channels have identical characteristics. The MAX11500 filter's -3dB frequency is 33MHz. The device includes a +6dB output buffer capable of driving a 2VP-P video signal into a standard 150 load. In the default configuration, the MAX11500 EV kit video inputs and outputs are set for AC-coupled operation. 2 The video inputs and outputs can also be configured for DC-coupled operation. The MAX11500 EV kit video inputs have a 75 termination to ground and the outputs are 75 back terminated. Jumper Selection AC-/DC-Coupled Input Operation The MAX11500 features a transparent clamp at the video inputs that allows for either AC- or DC-coupling. If the input signal remains above ground, the transparent clamp is inactive, offering true DC-input coupling. If the signal goes below ground, it must be AC-coupled. The transparent clamp will set the sync tip just below ground. Jumpers JU1, JU3, and JU5 set the MAX11500 EV kit video inputs for AC- or DC-coupled operation. For ACcoupled operation, remove shunts from jumpers JU1, JU3, and JU5. For DC-coupled operation, install shunts across jumpers JU1, JU3, or JU5. Use DC-coupling only for input signals whose lowest voltage is above ground. See Table 1 for proper jumper settings. When interfacing DC-coupled signals to the MAX11500 EV kit VIDIN_ inputs, verify that shunts are not installed across jumpers JU2, JU4, or JU6. Table 1. AC-/DC-Coupled Input Operation (JU1, JU3, and JU5) SHUNT POSITION EV KIT INPUTS Not installed AC-coupled operation Installed DC-coupled operation DC Bias for YPBPR Signals When configuring the EV kit video inputs for ACcoupled operation, the correct DC bias point has to be chosen, depending on the input signal. Unipolar signals, such as R, G, B, and Y, are biased correctly using the MAX11500 internal transparent clamp. For bipolar signals, such as PB and PR signals, a constant DC bias voltage has to be applied after the AC-coupling capacitor to make sure that the clamp never operates. A 590mV DC bias voltage can be applied by installing shunts across jumpers JU2, JU4, or JU6. To configure the inputs to a different DC bias voltage, replace resistors R2, R5, or R8. See Table 2 for input clamp configuration. Table 2.
