SG-9101CG-D40PHCAA

Overview

The EPSON SG-9101CG-D40PHCAA is a programmable spread spectrum crystal oscillator (XO) with CMOS output. It operates within a frequency range of 670 kHz to 170 MHz and supports a supply voltage of 1.62V to 3.63V. The device features enable/disable functionality and downward spread spectrum modulation. It is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm. The component is rated for an operating temperature range of -40°C to +105°C and complies with RoHS3 standards.

Feature Summary

• Supports programmable frequency generation across a wide range from 670 kHz to 170 MHz
• Integrates downward spread spectrum modulation to reduce electromagnetic interference
• Includes hardware enable and disable control for power management optimization

Applications

• High-speed data transmission interfaces requiring low jitter clock sources
• Embedded systems and microcontroller units needing precise timing signals
• Consumer electronics devices sensitive to electromagnetic compatibility requirements

Procurement Notes

This specific part number indicates a factory-programmed unit with predefined frequency and spread spectrum settings. Verify that the required operating frequency falls within the 670 kHz to 105°C industrial temperature range specifications. Ensure the design accommodates the 1.62V to 3.63V supply voltage constraints. Confirm that the 4-SMD no-lead footprint matches the PCB layout dimensions of 2.50mm by 2.00mm. Check for RoHS3 compliance if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a small form factor programmable oscillator with integrated spread spectrum capabilities is required. It is suitable for designs where reducing EMI is critical without adding external filtering components. Choose this series over fixed-frequency crystals when system flexibility or multiple frequency options are needed. Consider the CMOS output drive strength and the enable pin functionality for power-sensitive applications. Verify thermal performance within the specified -40°C to +105°C range for the intended environment.

Part Context

The SG-9101CG-D40PHCAA belongs to the EPSON SG-9101 series of programmable spread spectrum crystal oscillators. This series is designed to provide high stability and low phase noise in a miniature surface-mount package. The CG suffix typically denotes the package type and temperature rating, while the D40 indicates the spread spectrum bandwidth characteristics. These oscillators are engineered for applications demanding precise clocking with minimized electromagnetic emissions.

Replacement Considerations

Direct replacements must match the 4-SMD no-lead package dimensions and CMOS output type. Compatible alternatives should support the same 1.62V to 3.63V supply range and -40°C to +105°C operating temperature. Verify that any substitute offers similar spread spectrum functionality if EMI reduction is required. Cross-reference pinouts and electrical characteristics to ensure circuit compatibility.
