Description
General part information
LE9540 Series
The Le9540 Dual Ringing SLIC device is a dual-channel device optimized to provide battery feed, ringing, and supervision on voice loops found in short-loop VoIP applications. This device is optimized with a serial bus to interface to the Broadcom BCM3383/84/85/90 cable SoCs and BCM6818/28/38 PON SoCs. The Le9540 device operates independently from a single, user-adjusted battery and a +3.3 V VCC per channel. Each channel provides 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.
