6U-4.000MBE-T

Oscillators Overview

The 6U-4.000MBE-T is a Voltage Controlled Crystal Oscillator (VCXO) manufactured by TXC Corporation, utilizing a crystal base resonator and CMOS output technology. It operates at a nominal frequency of 4.0000 MHz with an absolute pull range of ±50 ppm. The device supports a supply voltage of 3.3V and features enable/disable functionality. Designed for surface mount installation, it is housed in a 4-SMD, no-lead package measuring 7.00mm x 5.00mm with a maximum height of 1.42mm. It functions within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Voltage controlled operation via crystal base resonator
• CMOS output signal generation
• Enable and disable control functionality
• Wide industrial operating temperature range

Oscillators Applications

• Clock signal generation in communication systems
• Frequency synthesis circuits
• Data transmission equipment requiring precise timing
• Embedded systems needing programmable clock sources

Oscillators Procurement Notes

Verify the specific suffix 'BE' confirms the 3.3V supply voltage and ±50ppm pull range requirements for your design. Ensure the 4-SMD footprint matches your PCB layout dimensions. Confirm that the CMOS output logic levels are compatible with your target microcontroller or FPGA inputs. Check for any RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a programmable frequency source is required rather than a fixed crystal. The VCXO architecture allows for frequency adjustment within the specified pull range. Consider the ±50ppm stability against your system's jitter tolerance. The 3.3V supply requirement must align with your power rail availability. The wide temperature range suits harsh environments where standard commercial parts may fail.

Oscillators Part Context

This part belongs to the 6U series of Voltage Controlled Crystal Oscillators from TXC Corporation. The series provides flexible clock solutions for applications requiring frequency tuning. The 6U-4.000MBE-T specifically addresses the need for a 4MHz reference with moderate pullability. It complements fixed-frequency oscillators by offering dynamic frequency control capabilities in a compact surface-mount package.
