I use the DIO2 pin on the ADIS16480 to indicate new data available. The edge rate on that pin is surprisingly slow: about 3 uS transition time.
In the scope trace below, blue is the DIO2 pin and yellow is the SPI SCK pin. Everything is working OK: the edge is triggering my AVR32 MCU to initiate a bunch of SPI reads to get the gyro data, and it triggers it reliably at 2.46 kHz. I just worry that the slow edge rate means that something is wrong, and it will cause multiple interrupts in a noisy environment.
Is the slow edge rate intentional? Configurable?
