ARA2000

Address-Programmable Reverse

Amplifier with Step Attenuator

Data Sheet - Rev 2.3

feAtuRes

• Low cost integrated amplifier with step attenuator

• Attenuation Range: 0-58 dB, adjustable in 1dB

increments via a 3 wire serial control

• Meets DOCSIS distortion requirements at a

+60dBmV output signal level

• Programmable address allows multiple parts to

share control bus

• Low distortion and low noise

• Frequency range: 5-100MHz

• 5 Volt operation

• -40 to +85 oC temperature range

ApplicAtions

• MCNS/DOCSIS Compliant Cable Modems

• CATV Interactive Set-Top Box

• Telephony over Cable Systems

• OpenCable Set-Top Box

• Residential Gateway

The ARA2000 is designed to provide the reverse path

amplification and output level control functions in a

CATV Set-Top Box or Cable Modem. It incorporates

a digitally controlled precision step attenuator that is

preceded by an ultra low noise amplifier stage, and

followed by an ultra-linear output driver amplifier. This

device uses a balanced circuit design that exceeds the

MCNS/DOCSIS requirement for harmonic performance

at a +60dBmV output level while only requiring a single

polarity +5V supply. Both the input and output are

matched to 75 ohms with an appropriate transformer.

The precision attenuator provides up to 58 dB of

attenuation in 1 dB increments. The ARA2000 has a

programmable address that allows multiple devices to

share a common control bus. The ARA2000 is offered

in a 28-pin SSOP package featuring a heat slug on

the bottom of the package.
