产品详情

The user guide explains the design and setup of the EVALADSP1802EBZ evaluation board. This evaluation board provides all digital applications interface (DAI) and digital peripheral interface (DPI) inputs/outputs by using jumpers and switches. The evaluation board is designed to be used in conjunction with the CrossCore Embedded Studio (CCES) environment to test the capabilities of the ADSP1802 processor, which interfaces to the EVAL-ADSP1802EBZ via the ICE-1000/ICE-2000 emulators. The EVAL-ADSP1802EBZ can be powered by an adapter or a 5 V supply. Any of these supplies are regulated to the voltages required on the EVAL-ADSP1802EBZ. The EVAL-ADSP1802EBZ contains four channels of analog-to-digital converter (ADC) input and eight channels of digital-to-analog converter (DAC) output. The core clock can be provided by a 25 MHz oscillator, crystal, or external CLK.
