LAYOUT INFORMATION

The schematic of the evaluation board (Figure 8) represents

a typical implementation of the AD10200. The pinout of the

AD10200 is very straightforward and facilitates ease of use and

the implementation of high frequency/high resolution design

practices. It is recommended that high quality ceramic chip

capacitors be used to decouple each supply pin to ground directly

at the device. All capacitors can be standard high quality ceramic

chip capacitors.

Care should be taken when placing the digital output runs.

Because the digital outputs have such a high-slew rate, the

capacitive loading on the digital outputs should be minimized.

Circuit traces for the digital outputs should be kept short and

connect directly to the receiving gate. Internal circuitry buffers

the outputs of the ADC through a resistor network to eliminate

the need to externally isolate the device from the receiving gate.

EVALUATION BOARD

The AD10200 evaluation board (Figure 9) is designed to

provide optimal performance for evaluation of the AD10200

analog-to-digital converter. The board encompasses everything

needed to ensure the highest level of performance for evaluating

the AD10200. The board requires an analog input signal, encode

clock and power supply inputs. The clock is buffered on-board

to provide clocks for the latches. The digital outputs and out

clocks are available at the standard 40-pin connectors J1 and J2.

Power to the analog supply pins is connected via banana jacks.

The analog supply powers the associated components and the

analog section of the AD10200. The digital outputs of the

AD10200 are powered via banana jacks with 3.3 V. Contact the

factory if additional layout or applications assistance is required.
