DESCRIPTION
The DS91D180 and DS91C180 are 100 MHz M-
LVDS (Multipoint Low Voltage Differential Signaling)
line driver/receiver pairs designed for applications
that utilize multipoint networks (e.g. clock distribution
in ATCA and uTCA based systems). M-LVDS is a
bus interface standard (TIA/EIA-899) optimized for
multidrop networks. Controlled edge rates, tight input
receiver thresholds and increased drive strength are
sone of the key enhancments that make M-LVDS
devices an ideal choice for distributing signals via
multipoint networks.
The DS91D180/DS91C180 driver input accepts
LVTTL/LVCMOS signals and converts them to
differential M-LVDS signal levels. The
DS91D180/DS91C180 receiver accepts low voltage
differential signals (LVDS, B-LVDS, M-LVDS, LV-
PECL and CML) and converts them to 3V LVCMOS
signals. The DS91D180 device has a M-LVDS type 1
receiver input with no offset.The DS91C180 device
has a type 2 receiver input which enable failsafe
functionality.
