CONFIDENTIALLe9530 Data Sheet Description The Le9530 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 to interface to the Broadcom BCM3378/3380/3382 and BCM6816 devices, or a similar codec. The Le9530 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. 2 Microsemi Corporation CONFIDENTIAL
