SN65MLVD2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SN65MLVD2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 SN65MLVD2 and SN65MLVD3 are single-channel M-LVDS receivers. These devices are designed in full

compliance with the TIA/EIA-899 (M-LVDS) standard, which are optimized to operate at signaling rates up to

250 Mbps. Each receiver channel is controlled by a receive enable (RE). When RE = low, the corresponding

channel is enabled; when RE = high, the corresponding channel is disabled.

The M-LVDS standard defines two types of receivers, designated as Type-1 and Type-2. Type-1 receivers

SN65MLVD2) have thresholds centered about zero with 25 mV of hysteresis to prevent output oscillations with

loss of input; Type-2 receivers (SN65MLVD3) implement a failsafe by using an offset threshold. Receiver

outputs are slew rate controlled to reduce EMI and crosstalk effects associated with large current surges.

The devices are characterized for operation from –40°C to 85°C.
