1 / 20 page  06/2004 ARA2000 Address-Programmable Reverse Amplifier with Step Attenuator Data Sheet - Rev 2.2 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.
