SG-8101CG 1.234567M-TCHSA0

Oscillators Overview

The SG-8101CG 1.234567M-TCHSA0 is a standard clock oscillator manufactured by Epson. It operates at a frequency of 1.234567 MHz with CMOS output levels. The device supports a supply voltage range of 1.8V to 3.3V and includes a standby (power down) function. Frequency stability is rated at ±20 ppm, and it functions within an operating temperature range of -40°C to +105°C. The component is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm.

Oscillators Feature Summary

• Integrated standby control for power management
• Compact surface-mount design suitable for space-constrained applications
• Wide operating temperature range ensuring reliability in harsh environments

Oscillators Applications

• Standard clock generation for digital circuits
• Timing reference for microprocessors and memory systems
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix TCHSA0 matches the required frequency and package variant. Confirm that the ±20 ppm stability and -40°C to +105°C temperature range align with system requirements. Ensure the 1.8V to 3.3V supply voltage compatibility is validated against the target circuit design before finalizing procurement.

Oscillators Selection Notes

Select this model when a precise 1.234567 MHz timing source is required with low power consumption capabilities. The wide temperature range makes it suitable for industrial or automotive-grade applications where environmental extremes are present. The CMOS output ensures direct interfacing with standard logic families without additional buffering.

Oscillators Part Context

This part belongs to the SG-8101CG series of standard oscillators from Epson. The series is characterized by small form factors and flexible supply voltage options. Variants within the series differ primarily by frequency, stability, and temperature grade, while maintaining consistent pinout and electrical characteristics for easy integration across different product lines.

Oscillators Replacement Considerations

Direct substitutes must match the 1.234567 MHz frequency, 4-SMD package, and ±20 ppm stability. Cross-referencing with other Epson models requires verifying identical pin configurations and voltage ranges to ensure functional compatibility without circuit redesign.
