Description

3" 240 400 widescreen color TFT LCD screen, STM32 is the master MCU, with the FPGA to implement the control and management of external ADC and data cache.
At the same time to reduce the size and easy to DIY manual welding, MCU and the FPGA are selected QFP100 package, ADC selected QFP48 package.
36M+36M sampling frequency, the use of the ADC AD9288-40 chip, single-channel maximum sampling frequency of the 72M.
FIFO RAM has a maximum operating frequency of use of> 200MHz low-power FPGA to achieve.
The AD9288-40 Overclocking to achieve 72M+72M sampling frequency, so that the maximum single-channel sampling rate up to 144M.
Analog channel circuit using unity gain> 150MHz op amp, so the actual 30MHz analog bandwidth is expected to do more.
As low power, low-cost, QFP package and other conditions of the FPGA, storage capacity is not large, so DSO203 sampling depth of the current situation for the multi-channel 4096 points per channel, single-channel work cases, 8192 points.
