QTM750S-100.000MBE-T

Overview

The QTM750S-100.000MBE-T is a surface-mount CMOS quartz oscillator manufactured by QST, operating at a frequency of 100 MHz. It utilizes HCSL output signaling and is housed in a compact SMD package. The device supports a supply voltage of 3.3V and offers an enable/disable control function for power management. It is designed for high-speed digital applications requiring precise clock signals with low jitter characteristics typical of the QTM750 series.

Feature Summary

• HCSL output interface for high-speed signal integrity
• Integrated enable/disable control pin for power optimization
• CMOS technology ensuring compatibility with standard logic families
• Surface-mount design for automated assembly processes

Applications

• High-speed data communication interfaces
• Network equipment clock distribution
• Server and storage system timing references
• Consumer electronics requiring precise synchronization

Procurement Notes

Verify the manufacturer designation carefully, as the part number prefix 'QTM' may be associated with TXC Corporation in some databases, while this specific suffix indicates QST production. Confirm the HCSL output type against your schematic requirements, as standard CMOS variants exist within the same series. Ensure the 3.3V supply voltage aligns with your system's power rails before procurement to avoid compatibility issues.

Selection Notes

Select this component when HCSL signaling is required for noise immunity in high-frequency designs. The 100 MHz frequency suits general-purpose clocking needs where moderate speed is sufficient. Consider the thermal performance within the -40 to 85°C range if operating in industrial environments. Compare against standard CMOS outputs if HCSL drivers are not present on the receiving end.

Part Context

This oscillator belongs to the QTM750 series, which provides various frequency options in a standardized footprint. The 'S' suffix typically denotes specific packaging or output configuration variations within the QST lineup. It serves as a direct replacement for legacy crystal oscillators in modern PCB layouts requiring reduced component count and improved reliability.

Replacement Considerations

Direct substitutes include other QTM750 series variants from QST with matching frequencies and HCSL outputs. Cross-reference with TXC QTM750 models only if electrical parameters like jitter and load capacitance are identical. Verify pinout compatibility before swapping manufacturers to prevent board redesign.
