Oscillators Procurement Notes

Verify the specific suffix 'D' indicates the enable/disable functionality if required by the circuit design, as this affects pin configuration. Confirm the operating voltage aligns with the 1.8V nominal requirement to ensure proper signal integrity. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure the supplier provides genuine TXC Corporation parts to guarantee frequency accuracy and reliability standards are met during production.

Oscillators Selection Notes

Select this component when a small form factor oscillator is needed for 38.4 MHz applications. The 1.8V supply voltage makes it suitable for modern low-power digital logic families. Consider the ±50 ppm stability sufficient for most synchronous data transfers. The ceramic construction offers robustness against mechanical shock compared to traditional glass-sealed crystals. Evaluate the enable/disable feature if power management strategies require clock gating capabilities.

Oscillators Part Context

This part belongs to TXC's 7CL series of low-profile CMOS oscillators. The series is designed for applications demanding miniaturization and low power consumption. The 38.4 MHz frequency is commonly used in telecommunications and networking equipment for baud rate generation. The ceramic variant provides a balance between cost, size, and performance for mass-produced electronic devices.

Oscillators Replacement Considerations

Direct substitutes include other 38.4 MHz CMOS oscillators in 2.5x2.0mm packages from manufacturers like Epson or Nihon Dempa Kogyo. Verify that replacement parts match the 1.8V supply voltage and ±50 ppm stability requirements. Ensure the pinout and enable/disable functionality are compatible with the existing PCB layout.
