125 MHz Quad M-LVDS Line Driver
General Description
The DS91M047 is a high-speed quad M-LVDS line driver de-
signed for driving 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 cur-
rent to handle double terminations that are required in multi-
point applications. Controlled transition times minimize re-
flections that are common in multipoint configurations due to
unterminated stubs.
The DS91M047 accepts LVTTL/LVCMOS input levels and
translates them to M-LVDS signal levels with transition times
of greater than 1 ns. The device provides the DE and DE in-
puts that are ANDed together and control the TRI-STATE
outputs. The DE and DE inputs are common to all four drivers.
The DS91M047 has a flow-through pinout for easy PCB lay-
out. The DS91M047 provides a new alternative for high speed
multipoint interface applications. It is packaged in a space
saving SOIC-16 package.
