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.
