ARA2005 General Description
The ARA2005 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 harmonicperformance at a +60 dBmV output level while only requiring a single polarity +5 V 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 via a three-wire serial interface. With external passive components, this device meets IEC 1000-4-12 and ANSI/IEEE C62.41-1991 100KHz ringwave tests, as well as IEC1000-4-5 1.2/50 S surge tests. The ARA2005 is offered in a 28-pin SSOP package featuring a heat slug on the bottom of the package.

operation is not implied under these conditions. Exposure to absolute ratings for
extended periods of time may adversely affect reliability.
Notes:
1. Pins 3, 5, 8, 10, 19, 20, 25 and 26 should be AC-coupled. No external DC bias should be
applied.
2. Pins 7 and 22 should be grounded or pulled to ground through a resistor. No external DC
bias should be applied.
