NJM2593V-TE1

Overview

The NJM2593V-TE1 is an RF demodulator integrated circuit manufactured by Nisshinbo Micro Devices Inc. It features a 50MHz input mixer and a 450kHz FM IF demodulator. The device operates on a supply voltage ranging from 1.8V to 9V, with a typical operating voltage of 2.5V. It supports a maximum power dissipation of 300mW and functions within a temperature range of -40°C to +85°C. The component is housed in an SSOP-20 package.

Feature Summary

• Integrates a 50MHz input mixer with a 450kHz FM intermediate frequency demodulator for signal processing.
• Designed for low current and low voltage applications to support battery-powered systems.
• Includes an internal RSSI comparator for monitoring received signal strength.

Applications

• FM receiver circuits requiring low power consumption
• Battery-operated wireless communication devices
• Voice transmission systems utilizing FM modulation

Procurement Notes

Verify the specific ordering suffix TE1 to ensure compatibility with reel packaging requirements. Confirm that the SSOP-20 package dimensions align with your PCB footprint specifications. Check RoHS compliance documentation for environmental regulatory adherence. Ensure the supplier provides valid traceability records for the Nisshinbo Micro Devices Inc. origin. Validate the operational temperature range against your system's thermal environment constraints.

Selection Notes

Select this component when a combined mixer and FM demodulator solution is required for frequencies up to 50MHz. Consider the low voltage operation capability if power efficiency is a primary design constraint. Evaluate the SSOP-20 package size relative to available board space. Compare the 300mW power dissipation limit against your thermal management capabilities. Verify that the 450kHz IF frequency matches your system's intermediate frequency architecture.

Part Context

The NJM2593V-TE1 belongs to the NJM2593 series of standard FM IF demodulators. This series is characterized by low current and low voltage operation suitable for portable applications. The component is categorized under Wireless & RF Integrated Circuits, specifically within the Modulator/Demodulator subcategory. It shares functional similarities with other parts in the series but is distinct in its 50MHz mixer input specification.
