PEF 4268 T V1.2

Product Brief SLIC-DC Ringing SLIC with Integrated DC/DC Converter P E F 4 2 6 8 T, P E F 4 2 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. Features 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. ■ ■ ■ ■ ■ ■ Applications ■ ■ ■ ■ ■ ■ ■ 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. 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 w w w. i n f i n e o n . c o m / p r o d u c ts Wireline Communications N e v e r s t o p t h i n k i n g . Product Brief SLIC-DC Block Diagram R1 unregulated supply voltage 9 .. 20V D QSW R2 C2 R3 L C C4 C3 R4 SENSE VS R6 CVR C1 C1 C2 C2 IO1 C3 DCP DCP DCN DCN ACP ACP ACN ACN C ITAC ITACA R IT1 DC/DC Converter R7 C6 C8 R8 EAN R9 C9 C10 R10 EAO VREF PEB4268 V1.2 SLIC-DC RP RL TIP IT ITA C7 COS SYNC Line-Interface SLIC-Interface (1 channel) GND Supply GNDA DUSLIC VN CODEC-Interface C1 L EMC SWD CEMC CL C EMC CL RING RIT2 RL RP VCM Product Summary Sales Code Description Package PEF 4268T SLIC-DC Subscriber Line Interface Circuit with Integrated DC/DC Converter P-DSO-24-8 PEF 4268F SLIC-DC Subscriber Line Interface Circuit with Integrated DC/DC Converter P-TQFP-48-1 SLIC-DC VoIP Application Exam ple Flash SDRAM SLIC-DC SLIC-DC SLIC-DC ADM5120 SLIC-DC Ethernet WAN t/r t/r t/r t/r 1 2 3 4 7 5 6 8 9 * 8 # 9...20/40 V Power Supply VINETIC-4 VIP 1 2 3 1 2 3 1 2 3 4 5 7 8 6 9 4 5 7 8 6 9 4 5 7 8 6 9 8 # * 8 # * 8 # * Four POTS Lines Computer How to reach us: http://www.infineon.com Published by Infineon Technologies AG, St.-Martin-Strasse 53, 81669 München © Infineon Technologies AG 2004.
