SG-8101CE-TJHPC

Overview

The SG-8101CE-TJHPC 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 frequency programming from 670 kHz to 20 MHz. The device includes an enable/disable function with a maximum supply current of 8.1mA during operation and 2.5 µA in standby mode. It is housed in a compact 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 1.20mm. The unit maintains a frequency stability of ±50ppm over the operating temperature range of -40°C to 105°C.

Feature Summary

• Offers flexible frequency programming capabilities across a wide range using standard CMOS outputs
• Integrates low-power standby functionality with minimal current consumption when disabled
• Provides stable clock generation with high frequency accuracy suitable for precision timing applications

Applications

• General-purpose digital systems requiring precise clock sources
• Embedded controllers and microprocessors needing programmable timing
• Portable electronic devices utilizing low-voltage power supplies

Procurement Notes

Verify that the specific ordering suffix matches the required frequency and package configuration. Confirm that the supplier provides official documentation for the programmed parameters. Ensure compatibility with the target system's voltage levels and interface requirements before finalizing the purchase order.

Selection Notes

Select this component when a fixed-frequency oscillator does not meet design flexibility needs. Consider the ±50ppm stability requirement against system jitter tolerance. Evaluate the 4-SMD footprint constraints against available PCB space. Verify that the 1.62V minimum supply voltage aligns with the system's power rail availability.

Part Context

This part belongs to the SG-8101 series of programmable crystal oscillators from EPSON Timing Solutions. The series is designed to replace multiple discrete crystal and oscillator combinations, simplifying bill-of-materials management. It utilizes internal quartz resonators to provide accurate clock signals without external tuning components.

Replacement Considerations

Direct replacements include other SG-8101CE variants with different frequency programming suffixes. Cross-reference pinout and electrical specifications carefully when substituting with similar programmable oscillators from other manufacturers.
