The ringing SLIC-DC with integrated DC/DC converter, is the latest

addition to Infineon’s family of SLIC products. The SLIC-DC provides cost

optimized solutions for CPE applications and requires only a single power

supply voltage. All POTS supply voltages are generated by the on-chip

DC/DC converter using only a few external components.

F e a t u r e s

■ Balanced ringing SLIC with integrated DC/DC

converter

■ Patented ring mode allows significant power

reduction

■ Uses robust technology based on Infineon’s

popular SLIC-E, PEB 4265

■ New interface towards VINETIC-2CPE.

Backward compatible to standard Infineon

Codec-SLIC interface, known from SLIC-S,

SLIC-E and SLIC-P

■ Minimized external component count in order to

enable high board density design

■ DC/DC output voltage up to -150 V

■ Single unregulated power supply voltage

between 9 V and 40 V. All other voltages are

generated internally.

■ Up to 85 Vrms sinusodial ringing

■ Fully programmable DC feed characteristic

■ Sensing of transversal line currents

■ Supports Integrated Test and Diagnostic

Function (ITDF), e.g. GR-909

■ Synchronization of up to 8 SLIC-DC’s

■ Low-cost BOM

Additional SLIC-DC features include a patented ring mode that significantly

lowers power consumption of the chip, with a corresponding lower heat

dissipation and total system power consumption. The SLIC-DC is also

offered in two packages to provide maximum design flexibility.

In combination with Infineon’s DuSLIC codec, the SLIC-DC can be used to

create xDSL or ISDN CPEs. The SLIC-DC is also highly suited for Analog

Telephone Adapter (ATA) and VoIP gateway solutions, when combined with

Infineon's VINETIC analog voice processor and the ADM5120SP CPU.
