SG-9101CE-C15PGDCA

Programmable Oscillators Overview

The SG-9101CE-C15PGDCA is a programmable spread spectrum crystal oscillator (XO) from Epson, featuring CMOS output and an enable/disable function. It operates on a supply voltage of 1.62V to 3.63V within a temperature range of -40°C to +85°C. The device supports frequencies from 670 kHz to 170 MHz in a 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 1.20mm maximum height. It utilizes center-spread modulation with a bandwidth of ±0.50% to reduce electromagnetic interference.

Programmable Oscillators Feature Summary

• Integrates spread spectrum technology to dynamically modulate clock frequency for EMI reduction
• Allows custom frequency programming via the SG-Writer II tool to suit specific design requirements
• Features internal compensation mechanisms that mitigate inherent aging effects and temperature drift found in fixed-frequency crystals

Programmable Oscillators Applications

• Automotive electronic systems requiring high electromagnetic compatibility
• Communication equipment needing precise clock signals with low noise
• Computer peripherals and general-purpose digital circuits

Programmable Oscillators Procurement Notes

Verify the exact part number suffix against official Epson documentation to ensure correct package dimensions and electrical specifications. Confirm that the required frequency falls within the supported range of 670 kHz to 170 MHz. Check for availability of the SG-Writer II programming tool if custom frequency generation is needed. Ensure the operating environment stays within the specified -40°C to +85°C industrial temperature limits.

Programmable Oscillators Selection Notes

Select this component when EMI suppression is critical for system compliance. The CE series offers a balance of performance and size suitable for space-constrained designs. Consider the ±0.50% center-spread bandwidth for optimal noise reduction. Verify power consumption requirements against the 1.62V to 3.63V supply range. Compare with other series like CG or CB if different package sizes or spread spectrum characteristics are required.

Programmable Oscillators Part Context

This model belongs to the SG-9101 series of programmable spread spectrum crystal oscillators. It is designed to replace traditional fixed-frequency crystals by offering adjustable parameters and enhanced stability. The series is widely used in applications demanding robust clock sources with minimized electromagnetic emissions across various industrial and consumer electronics sectors.

Programmable Oscillators Replacement Considerations

Direct substitutes include other SG-9101 series variants such as SG-9101CB or SG-9101CG models, provided they match the required frequency and package dimensions. Verify pin compatibility and electrical specifications before substitution. Consult Epson's official cross-reference guides for confirmed equivalent part numbers.
