SG-8101CA 41.6570M-TBGPA0

Oscillators Overview

The SG-8101CA 41.6570M-TBGPA0 is a standard crystal oscillator (XO) manufactured by EPSON, designed for precise clock signal generation in electronic systems. It operates at a nominal frequency of 41.657 MHz with a frequency stability of ±15 ppm. The device supports a supply voltage range of 1.8V to 3.3V and features CMOS output logic. It includes an enable/disable function for power management, drawing a maximum supply current of 6.8mA during operation and up to 3.5mA when disabled. The component is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm, suitable for surface mount applications across a temperature range of -40°C to 85°C.

Oscillators Feature Summary

• Integrated enable/disable control pin for active power management
• CMOS output compatible with standard digital logic interfaces
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• General purpose clock signal generation for embedded systems
• Timing reference for microcontrollers and processors
• Data communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix TBGPA0 matches the required tolerance and packaging configuration. Confirm that the 41.657 MHz frequency aligns with system timing requirements. Ensure the 1.8V to 3.3V operating voltage range is compatible with the target circuit supply rails. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Oscillators Selection Notes

Select this model when a stable 41.657 MHz reference is needed with low power consumption capabilities. The ±15 ppm stability suits general timing applications rather than high-precision RF uses. Consider the enable feature if system-level power saving is required. The small footprint allows integration into space-constrained PCB layouts compared to larger through-hole alternatives.

Oscillators Part Context

This component belongs to the SG-8101 series of standard crystal oscillators from EPSON Timing Devices. The series offers various frequencies and packages, providing designers with flexible options for clock generation. The SG-8101CA variant specifically denotes the CMOS output type within this family, ensuring broad compatibility with common digital logic families used in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 41.657 MHz frequency, 4-SMD package dimensions, and CMOS output characteristics. Verify that alternative sources offer equivalent ±15 ppm stability and 1.8V-3.3V operating ranges. Cross-reference pinouts and enable functionality to ensure electrical compatibility without redesigning the host circuit.
