Overview
The QTM252J-2.048MBJ-T is a standard clock oscillator manufactured by TXC Corporation under the QST brand, featuring a 2.5x2.0 mm surface-mount package. It operates at a frequency of 2.048 MHz with CMOS output logic and supports a supply voltage of 3.3V. The device offers enable/disable functionality and maintains a frequency stability of ±50ppm across an operating temperature range of -40°C to +105°C.
Feature Summary
- Provides low jitter and phase noise performance for precise timing applications
- Integrates enable and disable control capabilities for power management
- Utilizes a compact 2.5x2.0 mm SMD ceramic package design
Applications
- Digital signal processing systems requiring stable clock references
- Communication equipment utilizing 2.048 MHz timing standards
- Embedded systems needing low-power oscillators with control features
Procurement Notes
Verify manufacturer designation as TXC Corporation despite QST branding in distributor listings. Confirm package dimensions match 2.5x2.0 mm requirements. Ensure supply voltage aligns with 3.3V specifications. Validate frequency stability meets ±50ppm tolerance needs. Check temperature range compatibility for industrial environments.
Selection Notes
Select this component when a 2.048 MHz CMOS oscillator with enable control is required. Consider the 3.3V supply constraint and industrial temperature range. Evaluate space limitations against the 2.5x2.0 mm footprint. Compare jitter specifications against system timing requirements.
Part Context
This part belongs to the QTM252J series of quartz crystal oscillators. The series includes various frequencies and voltage options. The QTM252J-2.048MBJ-T specifically addresses 2.048 MHz applications with 3.3V operation. It shares common characteristics with other members of the family regarding package size and output type.
Replacement Considerations
QTM252J-14.7456MBJ-T: Same package and voltage but different frequency. QTM252J-11.2896MBJ-T: Same package and voltage but different frequency. QTM252J-48.000MDJ-T: Different voltage (1.8V) and frequency.
