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.

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.
