ARA2001S23P0

Overview

The ARA2001S23P0 is a narrow band low power amplifier utilizing GaAs technology in a 28-pin SSOP package. It operates on a 5V supply and supports a frequency range of 5 MHz to 100 MHz. The device features an integrated step attenuator with a range of 0-56 dB, adjustable in 2 dB increments via a 3-wire serial control interface. It includes a programmable address for bus sharing and a programmable 2-bit data port output. The unit meets DOCSIS distortion requirements at +60dBmV output signal levels.

Feature Summary

• Integrated step attenuator with 0-56 dB range adjustable in 2 dB increments
• Programmable address enabling multiple devices to share a common control bus
• Low distortion and low noise performance suitable for CATV applications
• On-chip switch allows amplifier shutdown and bypass to save power

Applications

• DOCSIS Compliant IP Telephony Systems
• CATV Interactive Set-Top Box
• OpenCable Set-Top Box
• Residential Gateway

Procurement Notes

Verify the specific revision status and lead time constraints directly with Anadigics or authorized distributors, as this component may be subject to lifecycle changes. Confirm that the 28-pin SSOP package with exposed paddle matches your PCB footprint requirements. Ensure compatibility with the required 3-wire serial control protocol and voltage levels for your system design before finalizing procurement orders.

Selection Notes

Select this component for systems requiring precise reverse path attenuation control within the 5-100 MHz band. It is suitable for designs needing multiple units on a single control bus due to its programmable addressing feature. Consider the 5V operation and GaAs construction when evaluating thermal management and power supply stability for residential gateway or set-top box implementations.

Part Context

This part belongs to the ARA series of address-programmable telephony reverse amplifiers manufactured by Anadigics. It is designed specifically for cable television infrastructure, providing both amplification and attenuation capabilities in a compact surface-mount package. The series supports interactive services and digital telephony over coaxial networks.

Replacement Considerations

The ARA3000S23P1 is a related model from the same manufacturer family, also featuring a 28-pin SSOP package and similar functionality. Verify pinout compatibility and specific electrical parameter differences before substitution.
