SG-9101CE-C02SGABB

Programmable Oscillators Overview

The SG-9101CE-C02SGABB is a programmable CMOS spread-spectrum oscillator from Epson's SG-9101Cx series. It operates within a frequency range of 670 kHz to 170 MHz and supports supply voltages between 1.62V and 3.63V. The device features a standby function with a maximum disable current of 3.7 mA. It is housed in a 4-SMD, no-lead package with a maximum seated height of 1.20 mm. The component is designed for industrial applications, supporting an operating temperature range of -40°C to +85°C.

Programmable Oscillators Feature Summary

• Integrates spread-spectrum technology to dynamically modulate clock frequency, suppressing spectral peaks to reduce electromagnetic interference.
• Allows users to customize spread-spectrum options, including span width, center or down-type spreading, modulation curves, and spreading curves via programming tools.
• Supports programmable frequency generation using the SG-Writer II tool, enabling design-specific frequency adjustments.

Programmable Oscillators Applications

• Automotive electronics requiring high electromagnetic compatibility
• Communication equipment needing EMI reduction
• Computer systems and peripheral devices

Programmable Oscillators Procurement Notes

Verify the specific ordering suffix against the official SG-9101Cx datasheet to ensure correct voltage, temperature grade, and packaging specifications. Confirm that the required spread-spectrum parameters are supported by the selected variant. Cross-reference the part number with the manufacturer's latest documentation to avoid discrepancies in electrical characteristics or pinout configurations.

Programmable Oscillators Selection Notes

Select this component when active EMI suppression is critical for system compliance. Ensure the design requires a programmable frequency solution rather than a fixed-frequency oscillator. Verify that the application environment falls within the specified industrial temperature range and voltage limits. Consider the need for custom spread-spectrum configuration during the design phase.

Programmable Oscillators Part Context

This part belongs to the SG-9101Cx series, which includes variants like SG-9101CA, CB, CE, CG, and CGA. The SG-9101CE variant specifically denotes the industrial-grade version available in the 3225 package size. Other series members may differ in temperature range, package dimensions, or automotive qualification status.

Programmable Oscillators Replacement Considerations

Direct substitutes must match the SG-9101Cx series specifications. No alternative part numbers are confirmed in the provided data. Any replacement must support identical programmability, spread-spectrum capabilities, and electrical parameters as defined in the official datasheet.

Programmable Oscillators FAQ

How is the spread-spectrum functionality configured?

The spread-spectrum options, such as span width and modulation type, can be customized by the user using the SG-Writer II programming tool.
