MAX3521

DOCSIS 3.0 Upstream Amplifier

General Description

Beneﬁts and Features

● +5V Supply Voltage

The MAX3521 is an integrated CATV upstream amplifier

IC designed to exceed the DOCSIS 3.0 requirements. It

provides a maximum output power level 3dB higher than

the DOCSIS 3.0 specification for all modulation standards

and channel configurations. The amplifier covers an 5MHz

to 85MHz input frequency range (275MHz, 3dB bandwidth).

It is capable of transmitting four QPSK modulated carriers,

each at +61dBmV, simultaneously within this range. The

gain is controlled in 1dB steps over a 63dB range using

an SPI 3-wire interface.

● Ultra-Low 25mW Dissipation in Transmit-Disable

Mode

● 63dB Gain-Control Range in 1dB Steps

● -65dBc Harmonic Distortion at 67dBmV Output

● Small 5mm x 5mm TQFN Package

● Low Burst On/Off Transient

● 275MHz, 3dB Bandwidth

● Multiple Power Modes for Optimal Battery Life

The device operates from a single +5V supply. Four power

codes are provided to allow maximum supply current to

be reduced as determined by distortion requirements.

In addition, for each power code, supply current is

automatically reduced as gain is reduced while maintaining

distortion performance. The supply current drops to 5mA

between bursts to minimize power dissipation in transmit-

disable mode. Control signal logic levels are 3.3V CMOS.

Applications

● DOCSIS 3.0 Plus Cable Modems and Gateways

● VOIP Modems

● Set-Top Boxes

The MAX3521 is the most recent addition to Maxim’s

pin-compatible cable upstream amplifier family, which

includes the MAX3518. The MAX3521 is available in a

20-pin TQFN package and operates over the extended

industrial temperature range (-40°C to +85°C).
