SG-8101CA 7.3828M-TBGPA0

Oscillators Overview

The SG-8101CA 7.3828M-TBGPA0 is a programmable standard crystal oscillator (SPXO) manufactured by Epson. It operates at a fixed frequency of 7.3828 MHz with CMOS output levels. The device supports supply voltages ranging from 1.8V to 3.3V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, no lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Programmable architecture allows for flexible frequency generation within the series capabilities.
• Integrated enable/disable pin provides efficient power management and standby control.
• CMOS output interface ensures compatibility with standard digital logic circuits.

Oscillators Applications

• General-purpose timing reference for embedded systems
• Clock source for microcontrollers and processors
• Communication module synchronization

Oscillators Procurement Notes

Verify the specific suffix TBGPA0 matches the required voltage range and load conditions. Confirm that the fixed 7.3828 MHz frequency aligns with the system design requirements, as this specific part number does not allow field reprogramming to other frequencies despite the series' general programmability. Ensure the 4-SMD footprint matches the PCB layout.

Oscillators Selection Notes

Select this component when a stable 7.3828 MHz clock is required with low-voltage operation between 1.8V and 3.3V. The enable feature is critical for battery-powered or power-sensitive designs. Consider the 4-SMD package size constraints during mechanical integration. This model is suitable for applications needing a fixed frequency derived from the programmable family rather than custom non-standard frequencies.

Oscillators Part Context

This part belongs to the SG-8101CA series of programmable SPXOs. While the series supports software-defined frequencies via tools like SG-Writer II, this specific SKU is pre-configured for 7.3828 MHz. It represents a balance between the flexibility of programmable oscillators and the cost-effectiveness of fixed-frequency components for mass production.

Oscillators Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Cross-referencing requires matching the 7.3828 MHz frequency, 1.8V-3.3V voltage range, CMOS output, and 4-SMD package dimensions.
