ATR2740-RQHH

Overview

The ATR2740-RQHH is a digital audio broadcasting (DAB) digital processing integrated circuit manufactured by Microchip Technology. It supports DQPSK modulation for broadcast radio applications and is housed in a 128-LQFP package measuring 14x14 mm with a 0.40 mm pitch. The device operates within a temperature range of -40°C to +85°C and utilizes surface mount technology.

Feature Summary

• Integrated digital processing for DAB broadcast radio signals
• Supports DQPSK modulation schemes
• Surface mount packaging for automated assembly

Applications

• Digital Audio Broadcasting receivers
• Broadcast radio signal processing units
• RF wireless communication modules

Procurement Notes

Verify the specific ordering suffix RQHH against official Microchip documentation to confirm the exact package variant and environmental rating. Ensure compatibility with existing PCB footprints for the 128-LQFP configuration before procurement. Cross-reference datasheet revisions to validate pinout consistency and electrical characteristics for the intended design implementation.

Selection Notes

Select this component when designing systems requiring dedicated hardware for DAB signal demodulation and processing. The choice depends on the need for integrated DQPSK handling and the physical constraints of the 128-LQFP surface mount package. Evaluate thermal requirements against the specified operating temperature range to ensure reliable performance in the target environment.

Part Context

This part belongs to the ATR2740 family of digital processing devices from Microchip Technology. The family includes variants such as the ATR2740-7GHG in a BGA121 package, offering different form factors for similar DAB processing functions. The RQHH suffix specifically denotes the LQFP package option within this product line.

Replacement Considerations

Direct substitutes include other ATR2740 family members like the ATR2740-7GHG if package adaptation is feasible. Verify functional equivalence and pinout compatibility before substitution. No alternative part numbers are confirmed as direct replacements without mechanical redesign.
