SG-8101CE-TCHSC

Overview

The EPSON SG-8101CE-TCHSC is a programmable CMOS crystal oscillator (XO) operating within the frequency range of 670 kHz to 20 MHz. It supports a supply voltage range of 1.62V to 3.63V and features a standby function for power management. The device is housed in a compact 4-SMD, No Lead package with dimensions of 2.5mm x 2.0mm. It exhibits a frequency stability of ±20ppm and operates across an extended temperature range from -40°C to +105°C. Typical supply current is 8.1mA, while disabled current is minimal.

Feature Summary

• Programmable frequency output capability within the specified low-frequency range
• Integrated standby mode for enhanced power efficiency during idle states
• Wide operating voltage range supporting both low-power and standard logic interfaces
• Compact surface-mount package design suitable for space-constrained applications

Applications

• General-purpose clock generation for embedded systems
• Timing reference for microcontrollers and digital signal processors
• Communication interface synchronization in portable devices
• Industrial control system timing sources

Procurement Notes

Verify the specific programmed frequency requirement against the 670 kHz to 20 MHz operational range before ordering. Confirm that the supply voltage aligns with the 1.62V to 3.63V specification to ensure proper operation. Check compatibility with the 4-SMD no-lead footprint for PCB layout integration. Ensure the application environment stays within the -40°C to +105°C temperature limits. Consult official documentation for programming procedures if custom frequencies are needed.

Selection Notes

Choose this component when a programmable solution is required for frequencies up to 20 MHz. It is suitable for designs needing wide voltage tolerance and low power consumption. Consider the ±20ppm stability for general timing needs rather than high-precision references. Evaluate the compact size against available board space constraints. Compare with fixed-frequency alternatives if programming flexibility is not required.

Part Context

This part belongs to the SG-8101 series of programmable oscillators from EPSON. It shares the same package and electrical characteristics as other variants in the family, differing primarily in the programmed output frequency. The series is designed for applications requiring flexible timing solutions in a small form factor.

Replacement Considerations

Direct substitutes include other SG-8101CE variants with different programmed frequencies but identical pinouts and specifications. Verify that any replacement maintains the 4-SMD no-lead package and compatible voltage range.
