The MAX101A evaluation kit (EV kit) was developed to assist in the initial evaluation of the MAX101A high-speed analog-to-digital converters (ADCs). The EV kit is a two-board set comprised of a main board and a termination board.
The main board contains all the circuitry needed to evaluate the initial performance of this flash converter, which combines high-speed analog and digital circuitry and requires special attention to circuit layout. In conjunction with the MAX101A, the main board allows digitizing of analog signals at up to 500Msps. It has provisions for an external clock source, which is supplied through an SMA connector. The analog inputs to the converter are through two SMA connectors (AIN+ and AIN-). There are 16 data outputs (two 8-bit words) plus the data clock output.
A separate termination board with 50Ω ECL pull-down resistors is provided with the kit and is connected to the main board with a 3x32 pin EURO-card connector. It provides access to the converter output data, as well as proper ECL termination. The termination board also has two ranks of square pins, each providing eight data outputs, plus data clock outputs. Either AData or BData can be observed with a high-speed logic analyzer.
Standard power supplies of +5V and -5.2V are needed to operate the MAX101A main board. Power can be supplied through the 3x32 EURO-card connector or through the pads on the edge of the board. Nominal power dissipation for both boards is 17W. The board set comes fully assembled and tested, with the MAX101A installed.
The MAX101A EV kit comes with a MAX101A installed on the board, but it can also be used to evaluate the MAX101. Refer to instructions for setting references and input conditions for the appropriate device version throughout this document.
