SG-9101CG-D40PGBAC

Overview

The SG-9101CG-D40PGBAC is a programmable spread spectrum crystal oscillator from Epson. It operates within a frequency range of 670 kHz to 20 MHz and supports CMOS output signals. The device functions with a supply voltage between 1.62 V and 3.63 V. It features an enable/disable control pin for power management. The component is housed in a compact 4-SMD surface-mount package without lead, designed for integration into space-constrained electronic circuits requiring precise clock generation.

Feature Summary

• Programmable spread spectrum functionality for electromagnetic interference reduction
• CMOS output signal compatibility with standard digital logic interfaces
• Integrated enable and disable control for active power management
• Compact 4-SMD surface-mount package design for board space efficiency

Applications

• General-purpose clock generation in embedded systems
• Timing reference sources for consumer electronics devices
• Clock distribution in industrial control equipment
• Signal synchronization in communication modules

Procurement Notes

Verify the specific ordering suffix D40PGBAC against the official Epson SG-9101Cx Series datasheet to confirm exact frequency and package specifications. Ensure that the required operating voltage range aligns with the system's power supply rails. Confirm RoHS compliance status through manufacturer documentation before procurement. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a programmable spread spectrum oscillator is required for EMI mitigation in low-frequency applications up to 20 MHz. Consider the CMOS output drive capability and the 1.62 V to 3.63 V supply range compatibility with the target system. Evaluate the 4-SMD footprint against available PCB real estate. Verify that the enable/disable feature meets the system's power sequencing requirements.

Part Context

This part belongs to the Epson SG-9101Cx series of programmable oscillators. The series offers flexible frequency programming and spread spectrum capabilities. These components are designed to replace fixed-frequency crystals in modern designs requiring noise reduction. The SG-9101CG variant specifically denotes the CMOS output type and standard package configuration within the broader product family.

Replacement Considerations

Consult the official Epson cross-reference guide for verified substitutes. Direct replacements must maintain the 4-SMD package and CMOS output characteristics. Ensure any alternative part supports the same 670 kHz to 20 MHz range and 1.62 V to 3.63 V operation. Verify that the substitute also includes programmable spread spectrum functionality if EMI reduction is critical.
