QTS532C-25.000MBP-T

Overview

The QTS532C-25.000MBP-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST, operating at a nominal frequency of 25 MHz. It utilizes CMOS output logic and requires a 3.3V supply voltage. The device features a frequency stability of ±0.28 ppm across the industrial temperature range of -40°C to +85°C. It is housed in a compact 10-SMD, No Lead package with dimensions of 5.0x3.2 mm. Maximum supply current is specified at 5 mA.

Feature Summary

• Integrates active temperature compensation circuitry for high-frequency stability
• Provides standard CMOS clock output signals
• Operates within an extended industrial temperature range

Applications

• Precision timing references in communication equipment
• Clock generation for digital signal processing systems
• Synchronization modules in network infrastructure devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the received parts match the specific ordering code QTS532C-25.000MBP-T, including suffixes indicating lead-free status and tape-and-reel packaging. Ensure storage conditions comply with moisture sensitivity levels defined in the datasheet to maintain reliability prior to soldering.

Selection Notes

Select this component when precise frequency accuracy is required over varying thermal environments. The ±0.28 ppm stability distinguishes it from standard crystals or less accurate oscillators. Verify that the system power budget accommodates the 3.3V supply and 5 mA current draw. Ensure the PCB layout supports the 10-SMD footprint and provides adequate shielding against electromagnetic interference affecting the TCXO performance.

Part Context

This part belongs to the QTS532C series of surface-mount TCXOs from QST. The series offers various frequency options and stability grades, with the 'BP' suffix denoting ±0.28 ppm stability. It serves as a higher-performance alternative to standard quartz crystals in applications demanding tight phase noise and frequency tolerance specifications.

Replacement Considerations

Direct substitutes include other QST TCXOs within the same 5.0x3.2mm package family, such as the QTS532C-26.000MBP-T, provided the frequency difference is acceptable. Cross-manufacturer replacements require matching pinout, voltage, and stability specifications.
