DS91C180屬于集成電路（IC）的驅(qū)動器接收器收發(fā)器。由美國德州儀器公司制造生產(chǎn)的DS91C180驅(qū)動器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進(jìn)行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

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.
