QTM750P-156.250MBE-T

Overview

The QTM750P-156.250MBE-T is a standard quartz oscillator manufactured by TXC Corporation, distributed under the QST brand. It operates at a frequency of 156.25 MHz with LVPECL output and supports 3.3V supply voltage. The device features enable/disable functionality and maintains a frequency stability of ±50ppm across an operating temperature range of -40°C to +85°C. It utilizes a crystal resonator in a 6-SMD, no-lead package measuring 7.00mm x 5.00mm x 1.50mm.

Feature Summary

• Differential LVPECL output configuration for high-speed signal integrity
• Integrated enable and disable control function for power management
• Surface-mount design compatible with automated assembly processes

Applications

• High-speed serial communication interfaces requiring precise clocking
• Network infrastructure equipment utilizing 156.25 MHz reference frequencies
• Test and measurement instruments demanding stable timing sources

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the received part matches the specific QTM750P-156.250MBE-T designation, noting the P-series variant characteristics. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Cross-reference datasheet specifications against current revision documents to validate performance parameters before integration into final assemblies.

Selection Notes

Select this component when differential LVPECL signaling is required for noise immunity in high-frequency applications. The 156.25 MHz frequency aligns with common telecommunications standards. Consider the 3.3V logic compatibility and compact 7.0x5.0mm footprint for space-constrained designs. Evaluate thermal performance within the specified -40°C to +85°C range to ensure reliability under operational stress conditions.

Part Context

This oscillator belongs to the BB series family from TXC Corporation, designed for surface-mount applications. The QTM750P variant specifically denotes the LVPECL output type within the broader QTM750 product line. It shares physical dimensions with other models in the series but differs in electrical output characteristics and pinout configurations suitable for differential clock distribution networks.

Replacement Considerations

QTM750P-156.250MBD-T serves as a documented substitute option within the same product family.
