QTO107-48.000MBL-T

Overview

The QTO107-48.000MBL-T is a quartz Oven Controlled Crystal Oscillator (OCXO) manufactured by TXC Corporation and distributed under the QST brand. It operates at a frequency of 48 MHz with a CMOS output format. The device utilizes an SC cut crystal resonator housed in a 9.7x7.5 mm surface-mount package. It functions on a 3.3V supply voltage and offers a frequency stability of +/- 20 ppb over the operating temperature range of -40°C to +85°C. The load capacitance is specified as 15 pF.

Feature Summary

• Integrates an oven-controlled mechanism for high-frequency stability across wide temperature variations
• Utilizes SC cut quartz crystal technology for precision oscillation
• Provides CMOS logic output compatible with standard digital interfaces

Applications

• Precision timing systems requiring stable clock references
• Telecommunications infrastructure equipment
• Test and measurement instruments

Procurement Notes

Verify the manufacturer designation, as this component is listed under both TXC Corporation and QST Products LLC. Confirm the specific suffix 'BL' indicates the +/- 20 ppb stability variant rather than the 'BV' variant which specifies +/- 10 ppb. Ensure the 48 MHz frequency matches the system requirement. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement.

Selection Notes

Select this component when a compact OCXO solution is required for applications demanding high stability within a limited thermal environment. The 3.3V supply voltage suits modern low-power digital designs. Compare against the QTO107-48.000MBV-T if tighter frequency tolerance of +/- 10 ppb is necessary. Ensure the 9.7x7.5 mm footprint fits the PCB layout constraints and that the CMOS output level aligns with the receiving circuit's input requirements.

Part Context

This part belongs to the QTO107 series of miniature OCXOs from TXC Corporation. The series includes variants with different frequencies, stability levels, and output formats. The QTO107-48.000MBL-T specifically denotes the 48 MHz version with BL suffix stability. Other models in the family include the QTO107-20.000MBV-T, offering different frequency and stability specifications within the same physical package form factor.
