ADN4690E屬于集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADN4690E驅(qū)動(dòng)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(zhǎng)電纜或印制線進(jìn)行通信。確切的功能會(huì)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(duì)于通信用途可能并非絕對(duì)必要，但對(duì)于可能的使用環(huán)境卻是明智之選。

GENERAL DESCRIPTION

The ADN4690E/ADN4692E/ADN4694E/ADN4695E are multipoint, low voltage differential signaling (M-LVDS) transceivers (driver and receiver pairs) that can operate at up to 100 Mbps (50 MHz). Slew rate control is implemented on the driver outputs. The receivers detect the bus state with a differential input of as little as 50 mV over a common-mode voltage range of ?1 V to +3.4 V. ESD protection of up to ±15 kV is implemented on the bus pins. The parts adhere to the TIA/EIA-899 standard for M-LVDS and complement TIA/EIA-644 LVDS devices with additional multipoint capabilities.
