VINETIC®-CPE Family Overview
2.5
SLIC-DC and SLIC-E
®
The VINETIC
-CPE family is able to interface with two SLICs from Infineon’s well-known SLIC family, the SLIC-DC
V1.2 and SLIC-E V2.1 (only for VINETIC-2CPE/-1CPE).
The SLIC-DC (PEF 4268 V1.2) is a high-voltage ringing Subscriber Line Interface Circuit with integrated DC/DC
converter. SLIC-DC is able to provide cost optimized solutions particularly in CPE applications, requiring only a
single power supply voltage between 9 V and 40 V. All the necessary POTS supply voltages are generated by the
on-chip buckboost DC/DC converter together with a minimum of external components. All CPE requirements on
the ring signal can easily be met, even for worst-case loads (e.g. 5 US-REN). SLIC-DC offers the unique feature
to reduce on-chip power dissipation. Reduced power and current requirements for the external DC/DC converter
components make a further contribution to the whole system cost reduction.
The High voltage ringing Subscriber Line Interface Circuit SLIC-E (PEF 4265 V2.1) is the latest out of the
wellknown and broadly used Infineon SLIC-E family. The highly flexible device offers 3.3 V compatibility and
integrated balanced ringing up to 85 V
. Integrated supply switches allow the choice between two negative
RMS
battery voltages for voice transmission, whereas in the ring mode an additional positive supply voltage is used.
The SLIC-DC simplifies the analog design of a FXS line so is recommended in VoIP CPE system, however the
overall system cost will be reduced by using the centralized DC/DC power supply and the SLIC-E, when a VoIP
CPE system has multi FXS lines, for example, an 8-16 channel FXS SOHO IP PBX.

VINETIC
-2CPE/-1CPE operates with either SLIC-DC or SLIC-E, whereas VINETIC
-2ATA/-1ATA operates with
SLIC-DC only.
SLIC-DC V1.2 is available with the two green package types PG-DSO-24-8 and PG-TQFP-48-1.
SLIC-E V2.1 is available in a single channel version (PEF 4265) in either P-/PG-DSO-20-24 or P-/PG-VQFN-48-4
power packages, or in a dual channel version (PEF 4365), packaged in P-/PG-DSO-36-10.
