DESCRIPTION  
FEATURES  
The Zarlink Le78D11 VoSLAC™ device has enhanced and  
optimized features to directly address the requirements of  
Voice over Broadband (VoB) applications. Their common goal  
is to reduce system level cost, board space, and power through  
higher levels of integration. In addition, this solution reduces  
the total cost of ownership of the end product by promoting  
higher quality of service through integrated line and self test  
capabilities. The VE770 series chip set uses two devices to  
provide a completely software configurable solution to perform  
the BORSCHT functions for two lines, including provision of a  
single line battery voltage. The resulting system is less  
complex, smaller, and denser, yet cost-effective with minimal  
external components.  
„ Integrated Dual-Channel Chipset  
— Switching regulator support  
— 44-pin TQFP Package  
— 3.3 V Operation  
„ Subscriber Loop Test/Self-Test  
— GR-909 compliant drop test capability in both  
measurements and pass/fail

Easy integration into the end application is enabled by the  
VoicePath™ API Software. Written in ANSI “C,” the software  
development kit reduces the complexity of adding voice into a  
product and makes use of the more sophisticated chip set  
functions, such as Caller ID. It includes a management tool that  
works with the WinSLAC™ Coefficient Generator to easily  
support multiple market applications.
