Single Ch Ringing SLIC with Serial Interface

Description

The Le9541 Single Ringing SLIC device is optimized for single channel designs to provide battery feed, ringing, and supervision on voice loops found in short-loop VoIP applications. This device utilizes a serial bus to interface to the Broadcom BCM3383/84/85/90 cable SoCs and BCM6818/28/38 PON SoCs. The Le9541 device operates independently from a single, user-adjusted battery and a +3.3 V VCC providing forward and reverse battery feed, voice transmission, power ringing, an ultra low-power scan state, ground start (Tip open), and a disconnect state. A test load switch is also included to support integrated test algorithms.
