Description
oscillator input; high-impedance node; minimize wire length
between quartz and package
oscillator output; high-impedance node; minimize wire length
between quartz and package
do not connect and do not use as feed through; connect to
V
test pin; not user accessible; connect to V
(internally pulled down)
interrupt output (open-drain; active LOW)
chip enable input (active HIGH) with internal pull down
ground
serial data output, push-pull; high-impedance when not
driving; can be connected to SDI for single wire data line
serial data input; may float when CE is inactive
serial clock input; may float when CE is inactive
CLKOUT enable or disable pin; enable is active HIGH
oscillator performance; recommend 100 nF decoupling close
to the device (see
clock output (open-drain)
supply voltage; positive or negative steps in V
