MDSL (Medium bit rate Digital
Subscriber Line) covers the sub
SDSL (Symmetric/Single Pair bit
rate DSL) rates at a granularity of
8 kbit/s. The
MuBIC 2
is the 2nd
generation of the Infineon MDSL
product family which fills the gap
between ISDN and SDSL.

Using the TC-PAM coding scheme
the
MuBIC 2
offers an excellent
transmission performance in
combination with a very low
interference with other services
like POTS, ISDN, HDSL, ADSL,
ADSL Lite and VDSL in the same
bundle. The exceptional low

s
power consumption of less than
500 mW at 1 Mbit/s meets
manufacturers requirements for
remote fed equipment e.g. for life
line service. The tiny TQFP-100
package contains a lot of
additional functionality like
framer and microcontroller.
