SLIC-DC Ringing SLIC with Integrated DC/DC Converter P E F 4 2 6 8 T, P E F 42 6 8 F 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. 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. • Customer Premises Equipment CPE • ISDN CPE • xDSL CPE • Analog Telephone Adapter • VoIP Gateways • Cable modems • Small PABX • 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.
