7C-133.3330MDE-T

Oscillators Overview

The 7C-133.3330MDE-T is a standard CMOS quartz oscillator manufactured by TXC Corporation, operating at a frequency of 133.333 MHz. It functions with a supply voltage of 1.8V and features an enable/disable control pin for power management. The device utilizes a 4-SMD, no-lead package with dimensions of 5.0 mm x 3.2 mm and a maximum height of 1.0 mm. It offers frequency stability of ±25 ppm over an industrial temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Integrates an enable/disable function for active power control
• Utilizes CMOS output format for digital logic compatibility
• Provides stable clock generation via quartz crystal technology

Oscillators Applications

• Communications equipment
• Wired networking systems
• Enterprise server infrastructure

Oscillators Procurement Notes

Verify the specific suffix 'MDE' against official datasheets to confirm the 1.8V supply voltage requirement, as other variants in the 7C series may operate at different voltages such as 3.3V. Ensure the lead frame material and termination finish match the target assembly process requirements. Confirm that the ±25 ppm stability specification meets the timing jitter constraints of the host system design before finalizing component selection.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for high-frequency clocking applications. The 4-SMD package size allows for compact PCB layout in space-constrained designs. Consider the enable/disable feature if dynamic power saving is necessary during idle states. Verify that the CMOS output swing is compatible with the input thresholds of the receiving logic gates in the circuit architecture.

Oscillators Part Context

This part belongs to the 7C series of standard oscillators from TXC Corporation, which are designed for general-purpose timing applications. The series includes various frequencies and voltage options, but the MDE suffix specifically denotes the 1.8V supply and 133.333 MHz frequency configuration. It serves as a direct replacement for legacy ceramic resonators where higher stability and lower phase noise are required.

Oscillators Replacement Considerations

Direct substitutes include the TA-133.330MBD-T, though it operates at 3.3V and requires level shifting or voltage adjustment. Other 7C series parts with identical pinout and frequency but different voltage ratings (e.g., 3.3V versions) require careful verification of power supply rails to prevent damage.
