7C-20.000MDB-T

Oscillators Overview

The 7C-20.000MDB-T is a standard CMOS crystal oscillator manufactured by TXC Corporation, operating at a nominal frequency of 20 MHz. It functions within a supply voltage range of 1.8V and features an enable/disable control function for power management. The device exhibits a frequency stability of ±25 ppm and supports a maximum supply current of 20 mA. Designed for surface-mount installation, it utilizes a compact 4-SMD, no-lead package with dimensions of 5.00mm x 3.20mm x 1.40mm. The component operates reliably across a temperature range of -10°C to +70°C.

Oscillators Feature Summary

• Integrated CMOS output stage providing standard logic compatibility
• Hardware enable/disable pin for active power state control
• Compact surface-mount footprint suitable for space-constrained designs

Oscillators Applications

• Digital signal processing clock sources
• Microcontroller system timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix 'MDB' against the manufacturer's official part number guide to confirm the exact voltage and stability specifications. Ensure the design accommodates the 4-SMD no-lead package dimensions and thermal requirements. Confirm RoHS3 compliance status if required by project regulations. Cross-reference the enable/disable functionality with the target circuit logic levels.

Oscillators Selection Notes

Select this component when a 20 MHz CMOS clock source with low power consumption is required. The 1.8V supply voltage makes it suitable for modern low-voltage digital systems. The ±25 ppm stability offers precise timing for sensitive applications. Consider the enable feature if dynamic power management is necessary. Verify that the operating temperature range meets the environmental conditions of the intended application.

Oscillators Part Context

This oscillator belongs to the 7C series from TXC Corporation, which focuses on tight stability performance. The series provides various voltage options and package sizes to support diverse embedded electronics needs. As a standard XO type, it integrates the resonator and oscillator circuit into a single surface-mount unit, simplifying PCB layout compared to discrete crystal solutions.

Oscillators Replacement Considerations

The 7C-20.000MBA-T is listed as a similar alternative, though it typically specifies a 3.3V supply in comparable listings. Verify voltage compatibility before substitution. Other variants in the 7C series may offer different stability or package options.
