7CL-48.000MDD-T

Oscillators Overview

The TXC Corporation 7CL-48.000MDD-T is a standard CMOS quartz oscillator operating at a frequency of 48 MHz. It features tight frequency stability of ±25 ppm across an extended temperature range from -40°C to +85°C. The device operates on a single 1.8V supply voltage and includes enable/disable functionality for power management. It utilizes a compact 4-SMD, no-lead package with dimensions of 5.0 mm x 3.2 mm, suitable for surface-mount assembly in space-constrained applications.

Oscillators Feature Summary

• Provides precise 48 MHz clock signal generation with ±25 ppm stability
• Operates within a wide industrial temperature range of -40°C to +85°C
• Supports low-voltage 1.8V operation with CMOS output levels
• Integrates hardware enable/disable control for efficient power management

Oscillators Applications

• High-speed data communication interfaces requiring stable clock sources
• Embedded systems and microcontroller platforms needing precise timing
• Industrial control equipment operating in extreme environmental conditions
• Portable electronic devices utilizing low-power CMOS logic families

Oscillators Procurement Notes

Verify the specific suffix 'MDD' corresponds to the required 1.8V supply voltage and ±25 ppm stability specifications. Confirm that the 5.0x3.2mm SMD footprint matches the target PCB layout. Ensure the design supports CMOS output levels and enables the disable pin if power conservation is required during idle states.

Oscillators Selection Notes

Select this component when strict frequency accuracy of ±25 ppm is mandatory over a wide thermal range. It is appropriate for designs constrained by low voltage availability (1.8V) rather than higher voltages like 3.3V. Consider the enable feature if system-level power cycling is necessary. Compare against series 7X or 7C if different voltage or size requirements exist.

Oscillators Part Context

This part belongs to the TXC 7CL series of standard clock oscillators. Unlike passive crystals, it provides a ready-to-use square wave signal. It differs from the 7X series which typically offers 3.3V operation, and the 7C series which may have wider tolerance or larger packages. The 7CL series focuses on tight stability in a small form factor for modern low-voltage digital circuits.

Oscillators Replacement Considerations

Direct substitutes include other 48MHz CMOS oscillators with 1.8V operation and ±25ppm stability in a 5.0x3.2mm package. Verify pinout compatibility and electrical characteristics before substitution. Generic replacements must match the enable/disable functionality and output drive strength.
