PRODUCTION DATA
This section demonstrates the use of the ADC12DL3200 in a reconfigurable oscilloscope. The oscilloscope can operate as a dual-channel oscilloscope running at 2.5 GSPS or can be reconfigured through SPI programming as a single-channel, 5-GSPS oscilloscope. This reconfigurable setup allows tradeoffs between the number of channels and the sampling rate of the oscilloscope as needed without changing the hardware. Set the input bandwidth to the desired maximum signal bandwidth through the use of an antialiasing, low-pass filter. Digital filtering can then be used to reconfigure the analog bandwidth as required. For instance, the maximum bandwidth can be set to 1 GHz for use during pulsed transient detection and then reconfigured to 100 MHz through digital filtering for low-noise, power-supply ripple observation. Figure 8-4 shows the application block diagram for a reconfigurable oscilloscope.
