com PBL 3798, PBL 3798/2 Subscriber Line Interface Circuit Description PBL 3798 is an analog Subscriber Line Interface Circuit (SLIC), which is fabricated in a 75 V bipolar, monolithic process.
The programmable, constant current 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 w...
