QTM750D-150.000MBE-T

Overview

The QTM750D-150.000MBE-T is a standard clock oscillator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 150.000 MHz and utilizes LVDS output signaling. The device features a frequency stability of ±50 ppm and supports an operating temperature range from -40°C to +85°C. Maximum supply current is specified at 50 mA. The component is housed in a compact surface-mount package suitable for automated assembly processes.

Feature Summary

• Generates precise 150 MHz timing signals using LVDS interface technology
• Maintains stable operation across industrial temperature ranges with high frequency accuracy
• Designed for direct surface-mount integration into printed circuit boards

Applications

• Digital signal processing controller synchronization
• Real-time system clock generation for embedded platforms
• High-speed data transmission interface timing

Procurement Notes

Verify the specific manufacturer designation when sourcing, as similar part numbers may exist under different branding or legacy designations. Confirm that the LVDS output requirement matches the receiving logic family voltage levels. Ensure the thermal environment remains within the specified -40°C to +85°C operational limits to maintain the stated ±50 ppm stability. Cross-reference the footprint dimensions against the mechanical drawing provided in the official datasheet before finalizing the PCB layout.

Selection Notes

Select this component when a low-jitter, high-frequency clock source is required for digital systems. The LVDS output provides noise immunity suitable for high-speed environments. Consider the 50 mA current consumption during power budget calculations. The wide temperature range makes it suitable for industrial or automotive-grade applications where environmental extremes are expected. Verify compatibility with the target system's voltage rails and load requirements.

Part Context

This oscillator belongs to the QTM750 series, which offers various frequency options within a standardized surface-mount form factor. The 'D' suffix typically indicates specific packaging or pinout variations within the product line. It serves as a critical timing reference for microprocessors and FPGAs requiring precise clock edges. The series is engineered to replace discrete crystal resonators and external driver circuits, simplifying board design and reducing component count.

Replacement Considerations

Direct substitutes include other QST oscillators from the same QTM750 family with matching frequency and output type. Verify pin-to-pin compatibility if swapping with equivalent parts from other manufacturers. Ensure that any alternative component supports the same LVDS swing and current drive capabilities to prevent signal integrity issues.
