DESCRIPTION  
The Zarlink Le9500 device, part of the VE950 series, is a  
subscriber line interface circuit (SLIC) 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 while  
providing ultra low power dissipation. The Le9500 SLIC device  
is capable of operating with a VCC supply of 3.3 V, and is  
designed to minimize external components required at all  
device interfaces. The differential ringing and receive inputs  
make the device ideal for direct interface to Data Over Cable  
Service Interface Specification (DOCSIS) compliant cable  
modem gateways, to multimedia adaptors, and to residential  
gateway products, such as the Broadcom® BCM3367/3368,  
BCM3341/3351/3352, BCM6353, BCM1101 and equivalent  
products.  
— Sine wave input - sine wave output  
— PWM input - sine wave output  
— Square wave input - trapezoidal output  
„ Flexible power supply options:  
— VBAT2 for active talking  
— VBAT1 for ringing, scan, and so on  
— 3.3 V for VCC  
„ Battery switch to minimize off-hook power  
„ Eight operating states:  
— Scan  
— Forward and reverse battery active  
— Forward and reverse battery on-hook transmission  
— Ground start  
— Ring  
— Disconnect
