AD8324集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書PDF中文資料

AD8324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AD8324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 AD8324 1 is a low cost amplifier designed for coaxial line driving. The features and specifications make the AD8324 ideally suited for DOCSIS 2.0 and Euro-DOCSIS applications. The gain of the AD8324 is digitally controlled. An 8-bit serial word determines the desired output gain over a 59 dB range, resulting in gain changes of 1 dB/LSB.

FEATURES

Supports DOCSIS 2.0 and Euro-DOCSIS standards for reverse path transmission systems

Gain programmable in 1 dB steps over a 59 dB range

Low distortion at 61 dBmV output:

–59 dBc SFDR at 21 MHz

–54 dBc SFDR at 65 MHz

Output noise level @ minimum gain 1.3 nV/√Hz

Maintains 75 Ω output impedance in TX-enable and Transmit-disable condition

Upper bandwidth: 100 MHz (full gain range)

3.3 V supply operation

Supports SPI? interfaces

APPLICATIONS

DOCSIS 2.0 and Euro-DOCSIS cable modems

CATV set-top boxes

CATV telephony modems
