Receiver power down control input or
programmable CMOS output. Refer to Function
Register Programming Description section for
details.
Transmitter power down control input or
programmable CMOS output. Refer to Function
Register Programming Description section for
details.
PLL power down control input. LOW for PLL
normal operations, and HIGH for PLL power
saving.
MICROWIRE
CMOS input with Schmitt Trigger.
MICROWIRE data input. High impedance
CMOS input with Schmitt Trigger.
MICROWIRE load enable input. High
impedance CMOS input with Schmitt Trigger.
Oscillator input. High impedance CMOS input
with feedback.
DC compensation circuit enable. While LOW,
the DC compensation circuit is enabled and the
threshold is updated through the DC
compensation loop. While HIGH, the switch is
opened, and the comparator threshold is held
by the external capacitor.
Received signal strength indicator (RSSI)
output.
Threshold level to external comparator.
™
clock input. High impedance
