SG-8101CE-TCHPC

Overview

The EPSON SG-8101CE-TCHPC is a programmable crystal oscillator (XO) featuring a CMOS output. It operates within a supply voltage range of 1.62V to 3.63V and supports frequencies from 670 kHz to 20 MHz. The device includes an enable/disable function, with maximum supply current at 8.1mA and disabled current at 3.5mA. Frequency stability is ±20ppm across the operating temperature range of -40°C to 105°C. It utilizes a 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 1.20mm.

Feature Summary

• Programmable frequency generation capability for customized clock requirements
• Integrated enable and disable control functionality for power management
• CMOS output interface compatible with standard digital logic circuits

Applications

• General purpose clock signal generation in embedded systems
• Timing reference sources for microprocessors and FPGAs
• Communication equipment requiring precise low-frequency clocks

Procurement Notes

Verify that the specific frequency requirement falls within the 670 kHz to 20 MHz operational range before ordering. Confirm that the system supply voltage remains strictly between 1.62V and 3.63V to ensure proper operation. Ensure the design accommodates the 4-SMD no-lead footprint dimensions of 3.20mm by 2.50mm. Check for any specific programming instructions required during the procurement process if custom frequencies are needed.

Selection Notes

Select this component when a fixed frequency is not sufficient and programmability is required. Compare against other SG-8101 variants to ensure the voltage range and package size match the target application constraints. Consider the ±20ppm stability specification against the system's timing tolerance requirements. Verify that the CMOS output swing is compatible with the receiving logic inputs.

Part Context

This part belongs to the SG-8101 series of programmable crystal oscillators manufactured by Epson Timing. The series offers flexibility through programmable frequency options while maintaining standard surface mount packaging. It serves as a versatile timing solution for applications needing customizable clock signals without sacrificing reliability or size constraints typical of modern electronic designs.

Replacement Considerations

Direct substitutes may include other SG-8101CE variants with different suffixes indicating distinct frequency programming capabilities or package variations. Verify compatibility with existing PCB footprints and electrical specifications before substitution.
