SG-9101CG-D40SHCAB

Overview

The SG-9101CG-D40SHCAB is a programmable XO (standard) CMOS oscillator from the EPSON SG-9101CG series. 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 a standby function with a maximum disabled current of 3.7 mA. It utilizes a crystal as the basic resonator and offers downward spread spectrum capability with a bandwidth of -4.00%. The component is housed in a compact 4-SMD, no lead package measuring 2.50mm x 2.00mm x 0.80mm.

Feature Summary

• Supports programmable frequency generation within a wide operational range using an onboard crystal resonator.
• Integrates a standby mode to reduce power consumption when the output is disabled.
• Provides downward spread spectrum functionality to minimize electromagnetic interference.
• Delivers standard CMOS output signals suitable for digital logic interfacing.

Applications

• General-purpose clock generation for embedded systems
• Timing reference for high-speed data communication interfaces
• Clock source for microprocessors and field-programmable gate arrays

Procurement Notes

This specific part number represents a pre-programmed unit. Verify that the factory-set frequency matches the design requirements exactly, as programmable oscillators are typically customized per order. Confirm the operating voltage range aligns with the target system's power rails. Ensure the 4-SMD package dimensions fit the PCB footprint constraints. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this model when a fixed-frequency solution derived from a programmable platform is required without custom programming delays. The CMOS output level simplifies interface design compared to LVDS or HCSL variants. Consider the -40°C to 105°C operating temperature range for industrial applications. The small form factor makes it suitable for space-constrained portable devices. Evaluate the standby current specification against total system power budgets.

Part Context

The SG-9101CG-D40SHCAB belongs to the SG-9101CG series of programmable spread spectrum crystal oscillators. This family is designed to offer flexibility in frequency selection while maintaining low jitter performance. The series supports various output types and voltage levels, catering to diverse electronic application needs across consumer, industrial, and automotive sectors.

Replacement Considerations

Direct substitutes include other SG-9101CG variants with matching frequencies and packages. Cross-reference pinouts and electrical specifications carefully. Alternative programmable oscillators may require firmware reconfiguration. Verify thermal characteristics and mounting compatibility before swapping components.
