Overview
The XR2211ACDTR-F is a telecommunications interface integrated circuit manufactured by MaxLinear, Inc., housed in a 14-SOIC package. It functions as an FSK demodulator and audio decoder designed for voiceband applications. The device operates on a supply voltage ranging from 4.5V to 20V with a typical supply current of 5mA. It supports a power dissipation of 900 mW and functions within an operating temperature range of 0°C to 70°C. The component is surface-mountable and has reached end-of-life status.
Feature Summary
- Integrated FSK demodulation capability for frequency-shift keying signal processing
- Built-in audio decoding functionality for voiceband communication systems
- Single-chip solution combining demodulator and decoder stages
Applications
- Voiceband data communication equipment
- FSK-based telemetry systems
- Audio decoding interfaces in telecommunications hardware
Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Verification of availability should focus on distributor surplus or secondary market sources rather than direct factory orders. Confirm the specific suffix 'F' corresponds to the required RoHS compliance status if applicable to your design constraints. Validate the 14-SOIC footprint compatibility during procurement review.
Selection Notes
Select this part only if the design requires a dedicated FSK demodulator and audio decoder within the specified 4.5V to 20V supply range. Ensure the 0°C to 70°C commercial temperature grade meets environmental requirements. Consider that the EOL status necessitates careful lifecycle management and potential redesign planning for long-term production support.
Part Context
The XR2211A series belongs to MaxLinear's legacy portfolio of telecommunications interface ICs. These components were historically utilized in modems and specialized communication devices requiring robust FSK signal handling. The XR2211ACDTR-F specifically denotes the tape-and-reel packaging variant of the AC grade device.
Replacement Considerations
As an EOL product, no direct official replacement is currently documented by MaxLinear. Designers must evaluate alternative FSK demodulators or discrete solutions. Verify pinout and functional compatibility if substituting with similar legacy parts from other manufacturers.
