7XL-155.520MDD-T

Oscillators Overview

The TXC Corporation 7XL-155.520MDD-T is a standard CMOS crystal oscillator operating at 155.52 MHz. It functions within a 1.8 V supply voltage range and features an enable/disable control function for power management. The device offers a frequency stability of ±25 ppm across the industrial temperature range of -40°C to +85°C. Housed in a compact 3.2 mm x 2.5 mm surface-mount package with a maximum seated height of 1.10 mm, it utilizes LVCMOS output format suitable for digital clock distribution applications.

Oscillators Feature Summary

• Integrated enable/disable functionality for dynamic power control
• Compact 3.2 mm x 2.5 mm SMD footprint design
• Industrial temperature range operation from -40°C to +85°C

Oscillators Applications

• Digital clock signal generation in communication equipment
• Data transmission interface timing sources

Oscillators Procurement Notes

Verify that the specific part number matches the required 1.8V supply voltage and LVCMOS output logic levels. Confirm the enable/disable pin configuration aligns with the target circuit design. Ensure the thermal performance meets the -40°C to +85°C operational requirements for the intended environment. Cross-reference the mechanical dimensions against the PCB land pattern to guarantee proper solder joint formation during assembly.

Oscillators Selection Notes

Select this component when a precise 155.52 MHz clock source is required with tight ±25 ppm stability. It is suitable for designs prioritizing low voltage operation at 1.8V over higher voltage alternatives. Consider the enable/disable feature if power efficiency is critical. Compare against other 7XL series variants if different frequencies or package sizes are needed for space-constrained layouts.

Oscillators Part Context

This oscillator belongs to the 7XL series by TXC Corporation, which specializes in tight-stability quartz oscillators. The series typically employs ceramic or quartz resonators housed in small SMD packages. These components are designed to replace larger through-hole crystals or less stable MEMS alternatives in high-density electronic assemblies requiring reliable timing signals.

Oscillators Replacement Considerations

Direct substitutes include other 155.52 MHz CMOS oscillators with identical 1.8V supply and ±25 ppm stability. Verify pin compatibility and enable/disable logic polarity before substitution. Alternative packages may require schematic modifications.
