L9500A Datasheet High-voltage Ringing Slic

Manufacturer: Agere Systems

Overview: Preliminary Data Sheet September 2001 L9500A High-Voltage Ringing SLIC for VoIP Applications L9500A Introduction The Agere Systems Inc. L9500A is a subscriber line interface circuit that is optimized for short-loop, power-sensitive applications. This device provides the plete set of line interface functionality (including power ringing) needed to interface to a subscriber loop. This device has the capability to operate with a VCC supply of 3.3 V or 5 V and is designed to minimize external ponents required at all device interfaces. This device is optimized to interface to data over cable service interface specification (DOCSIS) pliant cable modem gateway, multi-media adaptor, and residential gateway products, such as the Broad® BCM3351, BCM3352, BCM6352, and BCM1101 and equivalent products.
