Oscillators Applications

• Embedded system clock sources requiring precise timing references
• Industrial control modules operating within commercial temperature ranges
• Communication equipment utilizing 44 MHz base frequencies
• Consumer electronics with limited board real estate constraints

Oscillators Procurement Notes

Verify the specific suffix 'MBC' against project requirements, as it denotes a distinct package variant compared to other series members like MBB or MBA. Confirm that the ±100ppm stability specification aligns with the target application's jitter tolerance. Ensure the 3.3V supply rail matches the host system's voltage domain before integration. Cross-reference the 4-SMD No Lead pinout with the official datasheet to prevent PCB layout errors during schematic capture.

Oscillators Selection Notes

Select this model when a 44 MHz frequency is strictly required alongside a 3.3V operating voltage. The ±100ppm stability offers a balance between cost and performance for general-purpose applications. Consider the enable/disable feature if dynamic power saving is necessary. Evaluate the 5.00mm x 3.20mm package size against available PCB area. Compare against alternative frequencies within the 7C series if exact matching is not feasible.

Oscillators Part Context

This component belongs to the TXC 7C Series, a line of low-power CMOS oscillators designed for portable and industrial electronics. The series provides various frequency options in standardized SMD packages. The 7C-44.000MBC-T specifically addresses the need for a 44 MHz clock source in a compact form factor. It complements other variants differing only in frequency or package dimensions within the same functional family.

Oscillators Replacement Considerations

The 7C-44.000MBA-T is documented as an upgrade alternative from the same manufacturer. Verify compatibility regarding package dimensions and pinout alignment before substitution. Ensure the replacement part meets the same electrical specifications, particularly the 3.3V supply and CMOS output levels.
