Notes
Connect to system ground
Connect to ASIC logic
controller V
Regulated, 2.7 to 3.6 volts
Connect to a ”quiet“ ground
This pin must be driven either high
or low. Do NOT float the pin.
Output is a low pulse for 1.6 s
when a light pulse is seen
Logic High turns on the LED. If
held high longer than ~ 20 s, the
LED is turned off. TXD must be
driven high or low. Do NOT float
the pin.
May be unregulated, 2.7 to 6 volts.
Connect to system ground via a
low inductance trace. For best
performance, do not connect to
GND or AGND directly at the part.
