DESCRIPTION
The STLVD112 is a low voltage differential to
LVTTL signal converter with enhanced loop-back
and crosspoint features. The synchronous design
allows a phase alignment between a clock and its
data; this means a better BER (Bit Error Rate)
performance.
The advanced 0.35µm technology makes the
STLVD112 suitable for data rates up to 200Mbit.
The main application field is SDH/SONET telecom
infrastructure. The STLVD112 flexible switch
architecture makes it easy to implement multiple
protection schemes in STM1 access systems.
Thanks to the flexible multiplexing allowed, it
becomes simple to redirect the data/clock signal
coming from the faulty access card to the spare
card. In normal mode the STLVD112 converts the
differential data levels of the LVDS and related
TSSOP
clock signal from (to) the line interface in LVTTL
level signals to (from) the backpanel. In addition
the switch functions prevent the equipment from
line interface faults. In fact, it is possible to switch
the signals coming from a different line interface to
the local line interface or the signals from the local
line interface to a different line interface.
