The MAX100 evaluation kit (EV kit) allows high-speed digitizing of analog signals at 250Msps, using the MAX100 ADC. All circuitry required to support the ADC is supplied. Data output is available in three formats: divide-by-1, divide-by-2, or divide-by-5 mode. Clocking is provided by an external clock source input through an SMA connector.
The MAX100 EV kit main board comes complete with a MAX100 high-speed, 8-bit flash ADC with strobed comparators, latched outputs, and an internal track/hold. Analog input to the board is through two SMA coaxial connectors, for use with either differential or single-ended inputs.
Signals from the main board include dual-output data paths that allow easy interfacing to external circuitry. These two outputs can be configured either to provide two identical fast outputs (A and B), or an 8-to-16 demultiplexer mode that reduces the output data rates to one-half the sample clock rate. This demux is internal to the MAX100 ADC and is one of the key features of this device.
A termination board with 50Ω ECL pull-down resistors is also supplied, and is connected to the main board with a 3x32 pin EURO-card connector. It provides access to the converter output data and provides proper ECL data termination. In addition to the pull-down resistors, this board has two ranks of square pins, each providing eight differential data outputs plus clock outputs. Either AData or BData may be observed with a high-speed logic analyzer.
Standard power supplies of +5V and -5.2V are needed to operate the MAX100 EV kit 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 12W. The board set comes fully assembled and tested, with the MAX100 installed.
