DESCRIPTION
The DS91C176 and DS91D176 are 100 MHz single
channel M-LVDS (Multipoint Low Voltage Differential
Signaling) transceivers designed for applications that
utilize multipoint networks (e.g. clock distribution in
ATCA and uTCA based systems). M-LVDS is a new
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 enhancements that make M-LVDS
devices an ideal choice for distributing signals via
multipoint networks.
The DS91C176/DS91D176 are half-duplex
transceivers that accept LVTTL/LVCMOS signals at
the driver inputs and convert them to differential M-
LVDS signals. The receiver inputs accept low voltage
differential signals (LVDS, B-LVDS, M-LVDS, LV-
PECL and CML) and convert them to 3V LVCMOS
signals. The DS91D176 has a M-LVDS type 1
receiver input with no offset. The DS91C176 has an
M-LVDS type 2 receiver which enable failsafe
functionality.
