Analog Devices Inc. EVAL-ADSP1802 Evaluation Kit

Analog Devices EVAL-ADSP1802 Evaluation Kit supplies all digital applications interface (DAI) and digital peripheral interface (DPI) inputs/outputs using jumpers and switches. The ADI EVAL-ADSP1802 board is developed to be used with the CrossCore Embedded Studio (CCES) environment to test the capabilities of the ADSP1802 processor, which interfaces to the EVAL-ADSP1802EBZ through the ICE-1000/ICE-2000 emulators. An adapter or a 5V supply powers the EVAL-ADSP1802EBZ. Any of these supplies are regulated to the voltages required on the EVAL-ADSP1802EBZ.

The EVAL-ADSP1802EBZ incorporates four analog-to-digital converter (ADC) input channels and eight digital-to-analog converter (DAC) output channels. A 25MHz oscillator, crystal, or external CLK can supply the core clock.
