QTM750DH-200.000MBE-T

Overview

The QTM750DH-200.000MBE-T is a surface-mount clock oscillator manufactured by QST, operating at a nominal frequency of 200.000 MHz. It utilizes LVDS output logic and requires a 3.3V supply voltage. The device features a frequency stability of ±50ppm and supports an extended operating temperature range from -40°C to +85°C. Maximum supply current is specified at 100mA. The component is housed in a compact 7.0x5.0 mm package designed for high-density circuit board applications.

Feature Summary

• LVDS differential output signaling for high-speed data transmission
• Extended industrial temperature rating for harsh environments
• Compact surface-mount form factor for space-constrained designs

Applications

• High-speed serial communication interfaces
• Data acquisition systems requiring precise timing
• Telecommunications equipment clocking

Procurement Notes

Verify the specific ordering suffix against official QST documentation to confirm output type and tolerance. Ensure the requested part matches the required 3.3V supply and LVDS logic levels. Confirm RoHS compliance status through manufacturer certificates prior to procurement. Validate that the supplier provides genuine components with traceable origin to prevent counterfeit risks.

Selection Notes

Select this oscillator when LVDS signaling is required for noise immunity in high-frequency applications. Consider the ±50ppm stability requirement against system jitter specifications. Verify the 7.0x5.0mm footprint compatibility with PCB layout constraints. Ensure the 3.3V supply rail can support the maximum 100mA current draw during operation.

Part Context

This component belongs to the QTM750 series of standard clock oscillators produced by QST. The series offers various frequencies and output types within a consistent small outline package. The DH suffix typically indicates specific packaging or handling characteristics within the product line. This model represents a mid-range frequency option suitable for digital signal processing applications.

Replacement Considerations

Direct substitutes must match the 200MHz frequency, LVDS output, 3.3V supply, and 7.0x5.0mm package dimensions. Verify pinout compatibility before substitution. Check if alternative manufacturers offer equivalent stability and temperature ratings. Cross-reference datasheets for any differences in drive strength or load capacitance requirements.
