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 complete 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 components required at all device interfaces. This device is optimized to interface to data over cable service interface specification (DOCSIS) compliant cable modem gateway, multi-media adaptor, and residential gateway products, such as the Broadcom® BCM3351, BCM3352, BCM6352, and BCM1101 and equivalent products.
