SG-8101CE-TCHSB

Overview

The SG-8101CE-TCHSB is a programmable crystal oscillator (XO) manufactured by EPSON, featuring CMOS output signals. It operates within a supply voltage range of 1.62V to 3.63V and supports frequencies from 670 kHz to 170 MHz. The device exhibits ±20ppm overall frequency stability and functions across an operating temperature range of -40°C to 105°C. Maximum supply current is 8.1mA, with standby current at 3.5mA. It utilizes a 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 1.20mm maximum height.

Feature Summary

• Programmable frequency generation capability via order specifications
• CMOS output signal compatibility for digital logic interfaces
• Integrated enable/disable functionality for power management

Applications

• General purpose clock source for embedded systems
• Consumer electronics requiring precise timing
• Industrial control modules needing wide temperature operation

Procurement Notes

Verify the specific frequency requirement during ordering, as this component is programmed upon request. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Ensure the supply voltage range of 1.62V to 3.63V matches the system design. Check RoHS compliance status if required by environmental regulations. Validate the operating temperature range against the application environment.

Selection Notes

Select this model when a custom frequency between 670 kHz and 170 MHz is needed without maintaining inventory for multiple fixed frequencies. Consider the CMOS output level for direct interfacing with microcontrollers or FPGAs. Evaluate the ±20ppm stability against system jitter requirements. Assess the small 3225 package size for space-constrained designs. Compare standby current consumption if power efficiency in sleep modes is critical.

Part Context

This part belongs to the SG-8101 series of programmable crystal oscillators from EPSON. The series is designed to offer flexibility in frequency selection while maintaining standard form factors. It serves as a drop-in replacement for fixed-frequency oscillators where design flexibility is prioritized over volume pricing advantages.

Replacement Considerations

Direct substitutes include other SG-8101CE variants with different suffixes indicating specific programming or packaging options. Verify pinout compatibility and electrical parameters before substitution.
