PBL3796 Datasheet | Ericsson

April 1997 .. PBL 3796, PBL 3796/2 Subscriber Line Interface Circuit Description PBL 3796 is an analog Subscriber Line Interface Circuits (SLICs), which are fabricated in a 75 V bipolar, monolithic process. The programmable battery feed is resistive with short-loop current limiting. A switch-mode regulator reduces on-chip power dissipation in the active state. In the standby state, power dissipation is further reduced, while still permitting 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...
