Description
40-kHz burst generator - output 1.
Clock input or crystal / ceramic resonator connection.
Crystal / ceramic resonator connection. Not connected when external clock is ap-
plied.
Clock output to slave IC
Pin for programming capacitor at the envelope detector.
Analog supply voltage (+5V).
Analog ground.
Analog ground.
Ultrasonic echo input.
Time reference select input (SEL40K=’1’ to select 40 kHz or SEL 40K=’0’ to select
400 kHz at OSCIN).
Alarm enable input (when ALEN =’0’, the outputs ALARM, WARN and LED are dis-
abled).
Master/slave configuration pin (MODE=’0’ to configure slave IC, MODE=’1’ To config-
ure master IC with delayed sync and MODE open, to configure master IC without
delayed sync)

tivity fixed)
(not connected)
Test / reset pin. A rising edge resets the IC. This pin should be left unconnected or
tied to VDD for normal operation.
Digital supply voltage (+5V).
Digital ground
Synchronization pin. This pin is configured as output if pin MODE=’1^’ and as input if
MODE=’0’.
Active-low signalling LED output (open drain).
