PREVIEW
Zarlink’s VoiceEdge™ VE950 Series offers high performance, voice over broadband
SLIC devices with universal differential ringing and codec interfaces optimized
for short loop, power-sensitive applications. Providing the complete function-
ality required for interfacing to a subscriber loop, the VE950 products maintain
ultra low power dissipation.
Differential ringing and receive inputs make the VE950 Series ideal for direct inter-
face to data over cable service interface specification (DOCSIS) compliant cable
modem gateways, multimedia adaptors, ONT/PON CPE and residential gateway
products. This Series is optimized to interface to Broadcom cable modem and
PON SoCs

APPLICATION
Zarlink’s VE950 Series consists of single-channel and dual-chan-
nel devices optimized to provide battery feed, ringing, and
supervision on short loop plain old telephone service (POTS)
loops. These devices are optimized to interface to SoCs with
an integrated codec.
The VE950 Series significantly increases design flexibility,
improves system performance and reduces system BOM cost.
The single- and dual-channel SLICs are offered in footprint com-
patible package options as well as voltage-grade options. This
enables the designer to develop one application for all world-
wide markets, saving both time and money. Each channel of
these SLICs can provide up to -145 V power ringing to the sub-
scriber loop through amplification of a low-voltage input. These
ultra-low power devices consume less power than any SLIC
solution available in the market. The VE950 SLICs have excel-
lent thermal performance, providing improved reliability and
simplified PCB layout compared to alternative SLIC solutions.
In addition to superior performance, the VE950 SLICs require
the fewest number of external components, translating to the
lowest BOM cost. The high voltage design and patent pending
Common Protection Reference (CPR) of the VE950 Series allows
developers to use alternative protection options, thereby low-
ering the cost of the protection BOM. The VE950 Series of SLIC
devices is fully compliant to all worldwide specifications and
provides designer with a world-class and field proven solutions.
