SGR-8002JA-PHM

Overview

The EPSON SGR-8002JA-PHM is a programmable crystal oscillator (XO) from the SG-8002 series, manufactured by Epson. It features a CMOS output and operates on a 5V supply voltage. The device supports a frequency range of 1 MHz to 55 MHz with a stability of ±100ppm. It includes enable/disable functionality and consumes a maximum current of 45mA during operation. The component is housed in a 4-SOJ package with a 5.08mm pitch, measuring 14.00mm x 8.65mm. It is designed for surface mount installation and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Programmable frequency generation within a specified range using standard crystal base resonator
• Integrated enable and disable control function for power management
• CMOS output signal type compatible with standard digital logic interfaces

Applications

• General purpose clock generation for embedded systems
• Timing reference for microcontroller-based circuits
• Synchronization source for digital communication modules

Procurement Notes

This component is officially listed as obsolete and no longer in production by the manufacturer. Procurement should be approached with caution due to limited availability through authorized channels. Verify authenticity carefully when sourcing from third-party distributors, as counterfeit parts may exist in the secondary market. Ensure that any available stock matches the exact part number and packaging specifications required for your design.

Selection Notes

Engineers selecting this part must account for its discontinued status and potential long-term supply risks. The fixed 5V supply requirement limits compatibility with low-voltage modern designs. Consider the ±100ppm stability specification against system timing requirements. The 4-SOJ package footprint requires specific PCB layout adjustments compared to smaller surface-mount packages. Evaluate alternative active components if future production volume is anticipated.

Part Context

The SGR-8002JA-PHM belongs to the SG-8002 series of programmable oscillators from Epson. This series is known for high-reliability surface-mount crystal oscillators. The JA suffix indicates the specific electrical characteristics and package type configuration within the family. The PHM suffix typically denotes the specific ordering or packaging variant processed by distributors like DigiKey for custom frequency programming.

Replacement Considerations

As an obsolete component, direct replacements are not guaranteed. Engineers should consult the manufacturer's official replacement guide or datasheet for cross-reference recommendations. Alternative solutions may require redesigning the power supply for 3.3V operation if newer models are selected. Verify pinout compatibility before substituting with other programmable oscillators.
