QTS750C-19.440MBP-T

Overview

The QTS750C-19.440MBP-T is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by QST Products, LLC. It operates at a nominal frequency of 19.440 MHz with a CMOS output interface. The device requires a 3.3V supply voltage and draws a maximum current of 5mA. Frequency stability is specified at ±280 ppb. It supports an operating temperature range from -40°C to +85°C and utilizes a 4-SMD, No Lead surface mount package.

Feature Summary

• Temperature compensated crystal oscillator design for enhanced frequency stability across varying thermal conditions
• CMOS output signal format compatible with standard digital logic circuits
• Surface mount construction in a compact leaded-free package for automated assembly

Applications

• Telecommunications equipment requiring precise clock synchronization
• Data communication interfaces needing stable timing references
• Electronic systems operating within extended industrial temperature ranges

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 3.3V supply rail can maintain stable voltage under peak current loads of 5mA. Ensure the PCB layout accommodates the 4-SMD footprint dimensions accurately to prevent mounting issues during surface placement processes.

Selection Notes

Select this component when a stable 19.440 MHz reference is required in space-constrained applications. Consider the ±280 ppb stability specification against system jitter requirements. Evaluate the -40°C to +85°C range suitability for the intended environmental conditions compared to standard commercial grade alternatives.

Part Context

This part belongs to the QTS750C series of TCXOs from QST Products. The series offers various frequency options within the same physical package and electrical profile. The 'BP' suffix typically denotes specific packaging or tape configuration details defined by the manufacturer's internal coding standards for surface mount devices.

Replacement Considerations

Direct replacements must match the 19.440 MHz frequency, 3.3V supply, CMOS output, and 4-SMD package. Verify pinout compatibility and thermal stability specifications. Cross-reference with other manufacturers offering similar TCXO form factors if QST inventory is unavailable.
