ARA2001 General Description

The ARA2001 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 ARA2001is offered in a 28-pin SSOP package featuring a heat slug on the bottom of the package.

Stresses in excess of the absolute ratings may cause permanent damage. Functional
operation is not implied under these conditions. Exposure to absolute ratings for
extended periods of time may adversely affect reliability.
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical specifications.
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.
