Electrical Characteristics
(continued)
Table 6. Analog Pin Characteristics
1. Loop closure threshold is programmed by resistor R
LCTH
from pin LCTH to pin DCOUT. The programming equation or relationship between
off-hook threshold and resistor value is different for active mode versus scan mode (see Applications section for more details).
2. This parameter is not tested in production. It is guaranteed by design and device characterization.
3. I
N
is the sourcing current at RTSN. Guaranteed if I
N
is within 5

A to 30
μ
A.
Table 7. PPM
* PPM signal should be ac-coupled into PPMIN.
