ARA2004
Reverse Amplifiers
Application:
Reverse Amplifier with Step Attenuator
Description:
The ARA2004 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.
Features:
- Low Cost integrated amplifier with step attenuator.
- Attenuation range: 0-58dB, adjustable in 1dB increments via 3 wire serial control.
- Meets DOCSIS distortion requirements at +60dBmV output signal level.
- Low distortion and low noise.
- Frequency range: 5-100MHz.
- 5 Volt operation.
- -40 to +85 deg C temperature range.
- RoHS Compliant Package Option
