applied, the ADIS16266 automatically starts up and begins
sampling sensor data, without requiring configuration commands
from a system processor. An addressable register structure and a
common serial peripheral interface (SPI) provide simple access to
sensor data and configuration settings. Many digital processor
platforms support the SPI with simple firmware level instructions.
The ADIS16266 provides several programmable features for
in-system optimization. The Bartlett window FIR filter length and
sample rate settings provide users with controls that enable noise
vs. bandwidth optimization. The digital input/output lines offer
options for a data ready signal that helps the master processor
efficiently manage data coherency, an alarm indicator signal for
triggering master processor interrupts, and a general-purpose
function for setting and monitoring system level digital controls/
conditions.
