Pin Name
I/O
Description
Peripherals
DTMF
O
This pin outputs dual tone signals to dial out the phone number. The load resistor should
not be less than 5k .
MUSIC
O
This pin outputs the single tone that is generated by the PFD generator.
TIP
I
Input pin connected to the tip side of the twisted pair wires. It is internally biased to 1/2
VDD whenthedeviceisinpower-upmode.ThispinmustbeDCisolatedfromtheline.
RING
I
Input pin connected to the ring side of the twisted pair wires. It is internally biased to 1/2
VDDwhenthedeviceisinpower-upmode.ThispinmustbeDCisolatedfromtheline.
RDET1
I
This pin detects ring energy on the line through an attenuating network.
RTIME
I/O
Schmitt trigger input and NMOS output pin which functions with RDET1 pin to make an
RC network that performs ring detection function.
LBIN
I
This pin detects battery low through external R1/R2 to determine threshold voltage.
