SG-8101CG-TCHSC

Overview

The SG-8101CG-TCHSC is a programmable crystal oscillator (XO) manufactured by EPSON. It features a CMOS output waveform and operates within a supply voltage range of 1.62V to 3.63V. The device supports frequencies from 670 kHz to 20 MHz with a standard frequency stability of ±20 ppm. It consumes a maximum current of 8.1 mA at 25°C and includes a standby function for power management. The component is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm. It is designed for operation across an extended temperature range of -40°C to +105°C.

Feature Summary

• Programmable frequency generation capability within the specified range
• Low-power standby mode functionality for energy efficiency
• CMOS output interface compatible with digital logic circuits
• Extended industrial temperature rating for reliable performance

Applications

• Portable consumer electronics requiring low power consumption
• Industrial control systems operating in variable temperatures
• Communication modules needing precise clock signals
• Embedded systems utilizing CMOS logic interfaces

Procurement Notes

Verify the specific frequency order code against EPSON documentation, as the base model number covers a wide range. Confirm that the TCHSC suffix corresponds to the required frequency tolerance and package type. Ensure the design-in process accounts for the 4-SMD no-lead footprint dimensions. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate supply voltage requirements match the system's power rail capabilities.

Selection Notes

Select this component when a programmable XO is needed with CMOS outputs and industrial temperature support. Consider the 1.62V to 3.63V supply range compatibility with the target system. Evaluate the 8.1 mA maximum current draw against power budget constraints. Verify that the 2.50x2.00mm package fits the PCB layout restrictions. Compare frequency stability requirements against the standard ±20 ppm specification.

Part Context

This part belongs to the SG-8101 series of programmable crystal oscillators from EPSON. The series is characterized by small form factors and low power consumption. The SG-8101CG variant specifically denotes the CMOS output type and extended temperature range. This family is widely used in applications requiring precise timing solutions in compact designs.

Replacement Considerations

Direct substitutes are not explicitly listed in public data. Cross-reference with other EPSON SG-8101 variants using different suffixes for frequency or package changes. Verify pinout and electrical parameters before replacing with generic programmable oscillators.
