SG-9101CG-D40SGCAA

Overview

The SG-9101CG-D40SGCAA is a programmable crystal oscillator (XO) manufactured by EPSON, designed for flexible frequency generation. It supports an output frequency range from 670 kHz to 170 MHz with CMOS output logic. The device operates on a supply voltage of 1.62V to 3.63V and features a standby function. It is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm. The component functions within an industrial temperature range of -40°C to +85°C and includes spread spectrum capabilities with a downward bandwidth of -4.00%.

Feature Summary

• Programmable frequency output capability across a wide range
• Integrated standby mode for power management
• Spread spectrum modulation for EMI reduction
• Compact surface-mount package design

Applications

• General-purpose clock generation in embedded systems
• Data communication interfaces requiring precise timing
• Industrial control equipment clock sources
• Consumer electronics with space constraints

Procurement Notes

This component is available as a programmed unit or can be ordered with custom frequency specifications through authorized distributors such as DigiKey. Buyers should verify the specific ordering suffixes to ensure the correct package type and programming status. Confirm that the required frequency falls within the 670 kHz to 170 MHz operational range before placing orders. Ensure compliance with RoHS3 standards if environmental regulations are a priority for the project.

Selection Notes

Select this model when a small form factor is critical due to its 2.5x2 mm footprint. It is suitable for designs requiring low voltage operation down to 1.62V. Engineers should consider the CMOS output compatibility with their target logic levels. The availability of spread spectrum features makes it appropriate for applications where electromagnetic interference mitigation is required without additional filtering components.

Part Context

The SG-9101 series represents Epson's line of programmable spread spectrum crystal oscillators. This specific model belongs to the CG variant family, which typically denotes standard performance characteristics within the series. The SG-9101 series is widely used in modern electronics where size and power efficiency are paramount, offering a versatile alternative to fixed-frequency oscillators.

Replacement Considerations

Direct replacements may include other models from the SG-9101 series with compatible pinouts and electrical specifications. Verify that any substitute part matches the 4-SMD no-lead package dimensions and the 1.62V-3.63V supply range. Cross-reference the output frequency range and CMOS logic compatibility to ensure functional equivalence in the target circuit.
