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 MLVDS

signals. The receiver inputs accept low voltage

differential signals (LVDS, B-LVDS, M-LVDS, LVPECL

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.
