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.
