说明The MAX104/MAX106/MAX108 evaluation kits (EV kits) are designed to simplify evaluation of the devices' analog-to-digital converters (ADCs). Each EV kit contains all circuitry necessary to evaluate the dynamic performance of these ultra-high-speed converters, including the power-supply generation for the PECL termination voltage (PECLVTT). Since the design combines high-speed analog and digital circuitry, the board layout calls for special precautions and design features.
Connectors for the power supplies (VCCA/VCCI, VCCD, VCCO, VEE), SMA connectors for analog and clock inputs (VIN+, VIN-, CLK+, CLK-), and all digital PECL outputs simplify connection to the EV kit. The four-layer board layout (GETek material) is optimized for best dynamic performance of the MAX104 family.
The EV kits come with a MAX104/MAX106/MAX108 installed on the board with a heatsink attached for operation over the full commercial temperature range.
