SG-8101CG-TCHSB

Overview

The SG-8101CG-TCHSB is a programmable crystal oscillator (XO) manufactured by EPSON, featuring a CMOS output waveform. It operates within a supply voltage range of 1.62V to 3.63V and supports frequencies from 670 kHz to 170 MHz. The device includes a standby function for power management. It is housed in a 4-SMD, no-lead package with dimensions of 2.50mm x 2.00mm x 0.80mm. The unit complies with RoHS standards and exhibits a frequency stability of ±20ppm over an operating temperature range of -40°C to +105°C.

Feature Summary

• Programmable frequency generation capability across a wide range
• Integrated standby function for reduced power consumption
• CMOS output signal compatibility
• Lead-free construction compliant with environmental regulations

Applications

• General clock signal generation in electronic systems
• Portable devices requiring low power operation
• Industrial equipment needing stable timing references
• Consumer electronics utilizing standard clock oscillators

Procurement Notes

Verify the specific frequency order code suffix against the required application specification, as the base model number covers a broad range. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Ensure the supply voltage requirements match the system's available rail, noting the 1.62V to 3.63V operational window. Check for RoHS compliance documentation if required by project standards.

Selection Notes

Select this component when a programmable solution is needed for frequencies up to 170 MHz with CMOS outputs. Consider the ±20ppm total frequency stability for applications tolerant to minor drift. The wide operating temperature range suits industrial or automotive environments. Evaluate the standby current reduction benefits if power efficiency is critical. Compare package size constraints against other available oscillator options.

Part Context

This part belongs to the SG-8101 series of standard clock oscillators from EPSON. It represents a programmable variant designed for flexibility in frequency selection. The series is known for compact surface-mount packaging and reliable performance. It serves as a timing source for microcontrollers, memory, and communication interfaces.

Replacement Considerations

Direct substitutes include other SG-8101CG variants with different frequency suffixes, such as SG-8101CG-TCHSA0. Cross-reference pinout and electrical specifications before substitution. Verify that alternative parts meet the same temperature and stability requirements.
