AD8018AR-REEL集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書(shū)PDF中文資料

AD8018AR-REEL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AD8018AR-REEL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(guò)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。

PRODUCT DESCRIPTION

The AD8018 is intended for use in single-supply (5 V) xDSL modems where high-output current and low distortion are essential to achieve maximum reach. The dual high-speed amplifiers are capable of driving low distortion signals to within 0.5 V of the power supply rail.

FEATURES

Ideal xDSL Line Drive Amplifier for USB, PCMCIA, or

PCI-Based Customer Premise Equipment (CPE). The

AD8018 provides maximum reach on 5 V supply,

driving 16 dBm of power into a back-terminated,

transformer-coupled 100 Ω while maintaining –82 dBc

of out-of-band SFDR.
