PBL3798 Datasheet (Ericsson) - Subscriber Line Interface Circuit

PBL3798, Subscriber Line Interface Circuit

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 dissipati
