PBL 3799, PBL 3799/2 Subscriber Line Interface Circuit
Description
PBL 3799 is an analog Subscriber Line Interface Circuit (SLIC), which is fabricated in a 75 V bipolar, monolithic process.
The programmable, resistive feed circuit incorporates a switch mode regulator to minimize on-chip power dissipation.
A stand-by state further reduces idle power dissipation, while allowing the supervisory functions to be active.
Tip-ring polarity is reversible without altering SLIC supervisory and voice frequency (vf) functions.
Tip and ring outputs can be set to high impedance states.
These and other operating states are activated via a parallel, four bit control ...
