353SB3A320T

Oscillators Overview

The CTS-Frequency Controls 353SB3A320T is a Voltage Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 32.0000 MHz. It utilizes an HCMOS output type and requires a 5V supply voltage. The device features enable/disable functionality and offers a frequency stability of ±50ppm. Maximum supply current is 30mA. It is housed in a 6-SMD, No Lead package with dimensions of 5.00mm x 3.20mm x 1.40mm. The operational temperature range spans from -40°C to +85°C.

Oscillators Feature Summary

• Voltage-controlled crystal oscillator architecture for precise frequency tuning
• HCMOS digital output interface compatible with standard logic levels
• Integrated enable and disable control function for power management
• Surface-mount design optimized for automated PCB assembly processes

Oscillators Applications

• Communication protocol synchronization systems
• USB clock synchronization circuits
• Precision data logging equipment timing references

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout, tolerance, and packaging configuration. Confirm that the selected variant matches the required frequency stability and output drive strength for the target application environment. Cross-reference the component marking with the physical device upon receipt to prevent substitution errors during production integration.

Oscillators Selection Notes

Select this component when a stable 32 MHz reference with voltage control capability is required within a compact surface-mount footprint. Ensure the system design accommodates the 5V supply requirement and the maximum 30mA current consumption. Verify that the ±50ppm stability meets the jitter and phase noise specifications of the downstream circuitry. Confirm compatibility with the HCMOS output swing levels used by the receiving logic gates.

Oscillators Part Context

This part belongs to the 353 series of VCXOs from CTS-Frequency Controls, designed for high-reliability timing applications. The series provides various frequency options in a standardized small outline package. The 353SB3A320T specifically addresses needs for synchronized data transmission where frequency agility and moderate stability are prioritized over ultra-low phase noise performance typical of higher-end series.

Oscillators Replacement Considerations

Direct substitutes include other 32 MHz HCMOS VCXOs in 6-SMD packages with similar 5V operation and ±50ppm stability. Verify pin-to-pin compatibility and electrical parameters before swapping. Consult the manufacturer's cross-reference guide for approved alternative part numbers within the same product family.
