ARA2004S12P9

Overview

The ARA2004S12P9 is an address-programmable reverse amplifier with a step attenuator, manufactured by Anadigics using GaAs technology. It operates on a 5 V supply and supports a frequency range of 5-100 MHz. The device provides attenuation from 0 to 56 dB in 2 dB increments via a 3-wire serial control interface. It features a programmable address for bus sharing and a programmable 2-bit data port output. The component is housed in a 28-pin SSOP package with an exposed paddle.

Feature Summary

Integrated step attenuator with 0-56 dB range adjustable in 2 dB increments
Address-programmable architecture allowing multiple devices to share a common control bus
Low distortion and low noise performance suitable for DOCSIS compliance
On-chip switch allows shutdown and bypass of the output amplifier stage

Applications

CATV Set-Top Box reverse path amplification
Cable Modem signal processing
IP Telephony Systems
Interactive Set-Top Box implementations

Procurement Notes

Verify the specific suffix S12P9 against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure compatibility with 5 V operation and 3-wire serial control requirements. Check for lead-free alternatives if RoHS compliance is mandatory, as original specifications may indicate non-compliance.

Selection Notes

Select this component for applications requiring precise reverse path gain control in cable systems. The programmable address feature simplifies multi-device management. Verify that the 5-100 MHz frequency range meets system requirements. Consider the thermal performance within the -40 to +85 °C operating range.

Part Context

The ARA2004 series addresses reverse path amplification needs in CATV infrastructure. It integrates amplification and attenuation functions into a single GaAs IC. This integration reduces board space and complexity compared to discrete solutions. The device supports standard control protocols for easy integration into existing set-top box designs.
