The DS91M125 is a 1:4 M-LVDS repeater designed for driving and distributing clock or data
signals to up to four multipoint networks.
M-LVDS (Multipoint LVDS) is a new family of bus interface devices based on LVDS
technology specifically designed for multipoint and multidrop cable and backplane applications. It
differs from standard LVDS in providing increased drive current to handle double terminations that
are required in multi-point applications. Controlled transition times minimize reflections that are
common in multipoint configurations due to unterminated stubs.
A single DS91M125 channel is a 1:4 repeater that accepts M-LVDS/LVDS/CML/LVPECL signals
and converts them to M-LVDS signal levels. Each output has an associated independent driver enable
pin. The DS91M125 input conforms to the LVDS standard.
The DS91M125 has a flow-through pinout for easy PCB layout. It provides a new alternative
for high speed multipoint interface applications. It is packaged in a space saving SOIC-16
