TXO972005-STO-5277

Oscillators Overview

The TXO972005-STO-5277 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by Siward. It operates at a fundamental frequency of 26 MHz and delivers a clipped sine wave output signal. The device is designed for low-power applications, drawing a maximum supply current of 1.5 mA while requiring a supply voltage of 1.2 V. Frequency stability is specified at ±500 ppb. The component supports an extended operating temperature range from -30°C to +85°C and utilizes a compact 4-SMD, no-lead surface-mount package with dimensions of 0.079 inches in length.

Oscillators Feature Summary

• Integrates temperature compensation circuitry to maintain high frequency precision across wide thermal variations
• Operates on a low 1.2V supply rail with minimal current consumption for power-sensitive designs
• Features a compact leaded surface-mount footprint suitable for space-constrained PCB layouts

Oscillators Applications

• GNSS and GPS receiver modules
• 5G telecommunications base station infrastructure
• Automotive Advanced Driver Assistance Systems (ADAS)

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure the correct frequency tolerance and package variant. Confirm that the 1.2V supply requirement aligns with the target system's power architecture before integration. Request the latest datasheet to validate the ±500 ppb stability specification under the intended operating temperature conditions.

Oscillators Selection Notes

Select this component when a stable 26 MHz reference is required for systems operating between -30°C and +85°C. The low supply current makes it suitable for battery-powered or energy-efficient devices. Ensure the design accommodates the 1.2V logic level and the specific 4-SMD footprint constraints during the layout phase.
