TB-4.000MBE-T

Oscillators Overview

The TB-4.000MBE-T is a standard MEMS oscillator manufactured by TXC Corporation, operating at a nominal frequency of 4.000 MHz. It supports supply voltages ranging from 2.5 V to 3.3 V and delivers CMOS output signals. The device maintains a frequency stability of ±50 ppm across an extended industrial temperature range of -40°C to +85°C. Housed in a compact surface-mount package, this component integrates enable/disable functionality for power management. It is designed for applications requiring reliable clock generation with low phase noise characteristics typical of MEMS technology.

Oscillators Feature Summary

• MEMS-based resonator structure providing enhanced shock and vibration resistance compared to traditional quartz crystals.
• Integrated enable and disable control function allowing for active power state management within the circuit.
• CMOS output format compatible with standard digital logic interfaces without requiring additional level shifting.

Oscillators Applications

• Synchronization sources for communication interfaces such as UART, SPI, or I2C buses.
• Timing reference components in portable electronic devices where size constraints are critical.

Oscillators Procurement Notes

Verify current availability status as the part is listed as obsolete in multiple distributor databases. Confirm if replacement parts are officially supported by the manufacturer before finalizing design implementations. Ensure that any substitute components meet the same electrical specifications and mechanical footprint requirements to maintain system compatibility.

Oscillators Selection Notes

Select this component when a small form factor and robust mechanical performance are required over traditional crystal oscillators. Consider the specific voltage requirements of the target system to ensure compatibility with the 2.5V to 3.3V operating range. Evaluate the need for enable/disable functionality to optimize power consumption in battery-operated applications.

Oscillators Part Context

This oscillator belongs to the TB series of MEMS devices from TXC Corporation, which focuses on high-reliability timing solutions. The series utilizes silicon-based resonators to offer superior performance against environmental stressors. This specific model represents a standard XO configuration within that product line, targeting general-purpose digital timing needs.

Oscillators Replacement Considerations

Direct substitutes include the 7C-28.63636MBE-T, though frequency differences must be evaluated. Other potential replacements should be sourced from official manufacturer lists to ensure parameter matching.
