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, LVPECL

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.
