353TB3A426T

Oscillators Overview

The CTS-Frequency Controls 353TB3A426T is a Voltage Controlled Crystal Oscillator (VCXO) operating at a fundamental frequency of 42.6 MHz. It utilizes an HCMOS output signal and requires a 2.5V supply voltage. The device features enable/disable functionality and maintains a frequency stability of ±50ppm. Designed for surface mount installation, it is housed in a compact 6-SMD, No Lead package with dimensions of 5.00mm x 3.20mm x 1.40mm. The component supports an industrial operating temperature range from -10°C to +60°C.

Oscillators Feature Summary

• Voltage controlled crystal oscillator architecture providing precise frequency tuning capabilities
• HCMOS digital output interface compatible with standard logic circuits
• Integrated enable and disable control function for power management
• Surface mount construction within a small form factor 6-pin package

Oscillators Applications

• Telecommunications equipment requiring stable clock signals
• Data communication systems utilizing high-speed serial interfaces
• Consumer electronics devices needing compact timing solutions
• Industrial control systems operating within specified temperature ranges

Oscillators Procurement Notes

Verify the specific suffix 'A' against the official CTS datasheet to confirm the -10°C to +60°C temperature rating, as other suffixes may indicate different environmental specifications. Ensure the 2.5V supply requirement aligns with the target system design. Confirm that the HCMOS output voltage levels are compatible with the receiving logic inputs before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a VCXO is required rather than a fixed-frequency XO. The 42.6 MHz frequency must match the system reference requirements. Consider the ±50ppm stability limit against application needs. The 2.5V supply voltage dictates power budget constraints. Verify that the enable/disable pin usage fits the system control logic. The 6-SMD package size is suitable for space-constrained PCB layouts.

Oscillators Part Context

This part belongs to the CTS 353 series of surface mount oscillators. The series offers various frequencies and supply voltages. The 353TB3A426T specifically denotes the 2.5V variant with the A suffix indicating the commercial/industrial temperature range. Similar parts include the 353LB3C426T which operates at 3.3V. The series provides standardized footprints for easy integration into existing designs.

Oscillators Replacement Considerations

The 353NB3C426T and 353TB3C426T are listed as similar alternatives by distributors. However, the 353TB3C426T typically specifies a 2.5V supply but may differ in temperature range or exact electrical parameters compared to the 'A' suffix version. Cross-reference the full datasheet specifications for any differences in frequency stability, current consumption, or pinout compatibility before substitution.
