SA614AD,602

Overview

The SA614AD,602 is a monolithic low-power FM IF system by NXP USA Inc., designed for mobile phone, ASK, and FSK applications. Operating at a frequency of 25MHz, it integrates two limiting intermediate frequency amplifiers, a quadrature detector, muting, and RSSI capabilities. The component is housed in a 16-SOIC (SOIC16_150MIL) surface-mount package with dimensions of 9.90 x 3.90mm and a height of 1.35mm. It contains 16 pins and complies with RoHS standards.

Feature Summary

• Integrates dual limiting intermediate frequency amplifiers within a single monolithic structure
• Incorporates a quadrature detector for signal demodulation
• Includes built-in muting functionality
• Features integrated Received Signal Strength Indicator (RSSI)

Applications

• Mobile phone RF systems
• Amplitude Shift Keying (ASK) receivers
• Frequency Shift Keying (FSK) receivers

Procurement Notes

Verify component authenticity through authorized distributors or official NXP channels due to the part's discontinued status. Confirm that the specific suffix matches the required packaging configuration. Ensure compliance with current environmental regulations such as RoHS and REACH before integration into new designs.

Selection Notes

Select this component for legacy designs requiring a complete FM IF solution with RSSI output. Consider the 25MHz operating frequency and 16-pin SOIC footprint during PCB layout. Evaluate power consumption requirements against the low-power specification. Assess availability constraints given the product's end-of-life status.

Part Context

This device belongs to the SA614 series of improved monolithic low-power FM IF systems. It represents an evolution in integrated RF front-end solutions, combining amplification, detection, and signal strength monitoring into a compact surface-mount package suitable for portable wireless communication devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product status is listed as obsolete, alternative components must be identified through independent engineering analysis rather than direct manufacturer substitution lists.
