STC22K33Q27-19.200M

Oscillators Overview

The STC22K33Q27-19.200M is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by Suntsu Electronics, Inc. It operates at a nominal frequency of 19.2 MHz and delivers a clipped sine wave output signal. The device functions with a supply voltage of 3.3V and draws a typical supply current of 2mA. It is housed in a compact 4-SMD, No Lead package, specifically the SMD2520 form factor. The component supports an operating temperature range of -30°C to +85°C and maintains a frequency stability of ±1.5ppm across this range.

Oscillators Feature Summary

• Temperature compensated crystal oscillator design for stable frequency generation
• Clipped sine wave output suitable for digital clocking applications
• Compact surface-mount package for automated assembly

Oscillators Applications

• Wireless communication modules requiring precise timing references
• Portable electronic devices with limited power budgets
• Industrial control systems operating in variable thermal environments

Oscillators Procurement Notes

Verify the specific suffix Q27 against official Suntsu documentation to confirm the exact temperature range and stability specifications. Ensure the required output waveform matches the clipped sine wave characteristic provided by this model. Confirm that the 3.3V supply requirement aligns with the target system's power architecture before procurement.

Oscillators Selection Notes

Select this component when a balance between low power consumption and high frequency stability is required in space-constrained designs. The 2mA current draw makes it suitable for battery-operated equipment. The wide operating temperature range ensures reliability in harsh industrial or outdoor environments where standard oscillators might fail.

Oscillators Part Context

This part belongs to the STC22 series of TCXOs from Suntsu Electronics. The series offers various frequency options and package types. The STC22K33Q27 variant specifically denotes the 3.3V supply and the associated performance characteristics defined by the Q27 suffix within the manufacturer's product line.

Oscillators Replacement Considerations

The STC22K33P27-19.200M is a related variant within the same series. Verify if the P27 suffix indicates a different temperature range or stability metric compared to the Q27 version. Cross-reference electrical parameters to ensure compatibility with existing circuit designs.
