7C-8.000MBB-T

Oscillators Overview

The 7C-8.000MBB-T is a standard CMOS crystal oscillator manufactured by TXC Corporation, operating at a nominal frequency of 8 MHz. It functions with a single 3.3V supply voltage and features an enable/disable control pin for power management. The device utilizes a 4-SMD, no-lead surface mount package measuring 5.00mm x 3.20mm x 1.40mm maximum height. Frequency stability is rated at ±50ppm over the specified temperature range. The output format is CMOS, suitable for digital clock applications.

Oscillators Feature Summary

• Integrated enable/disable functionality for active power control
• CMOS output signal compatible with standard logic families
• Compact surface-mount footprint for automated assembly

Oscillators Applications

• Digital system clock generation
• Microprocessor timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix 'MBB' to confirm the 3.3V supply voltage and enable/disable feature set, as other suffixes in the 7C series may indicate different voltages or pin configurations. Ensure the ordering quantity matches the manufacturer's standard reel size of 1,000 units to avoid partial reel handling issues during production.

Oscillators Selection Notes

Select this component when a low-cost, standard-frequency CMOS oscillator with power gating is required. Confirm that the ±50ppm stability meets the system's jitter tolerance requirements. Verify that the 3.3V operating voltage aligns with the target board's power rails before finalizing the design.

Oscillators Part Context

This part belongs to the TXC 7C series of standard oscillators. The series offers various frequencies and packages, but the MBB suffix specifically denotes the 3.3V enable/disable variant. It serves as a fundamental timing source for embedded systems requiring precise clock signals without the complexity of programmable devices.

Oscillators Replacement Considerations

The 7C-8.000MBA-T is a documented substitute within the same family. Verify if the alternative suffix implies identical electrical characteristics and pinout compatibility before substitution.
