XTL5C1120-Q23-055

Crystals Overview

The Siward XTL5C1120-Q23-055 is a surface-mount crystal oscillator operating at a fundamental frequency of 76.8 MHz. It features an integrated thermistor for temperature compensation and stability. The component exhibits a frequency tolerance of -10 ppm to +22 ppm and has a load capacitance of 7 pF. Equivalent series resistance (ESR) is specified at 30 Ohms. The device utilizes a 4-SMD, No Lead package with dimensions of 0.065 inches in length.

Crystals Feature Summary

• Integrates a thermistor for enhanced thermal stability
• Fundamental resonance mode operation
• Surface-mount design for automated assembly

Crystals Applications

• Precision timing circuits requiring thermal compensation
• Communication systems utilizing 76.8 MHz reference clocks
• Embedded devices needing stable frequency sources

Crystals Procurement Notes

Verify the specific ordering suffixes to ensure compatibility with required packaging options such as cut tape or tape and reel. Confirm that the 4-SMD no-lead footprint matches the target PCB layout. Ensure the thermistor integration aligns with the system's thermal management strategy. Cross-reference the -10ppm/+22ppm tolerance against application requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 76.8 MHz fundamental frequency is required alongside built-in thermal monitoring capabilities. The 7pF load capacitance must match the circuit design specifications. Consider the 30 Ohm ESR value for impedance matching purposes. The 4-SMD package is suitable for high-density surface-mount applications where space constraints are critical.

Crystals Part Context

This part belongs to Siward's portfolio of frequency control components, specifically designed for applications demanding precise timing. The inclusion of a thermistor distinguishes it from standard crystals by providing active temperature-related data or compensation. It serves as a passive resonator element within oscillator circuits rather than an active output generator.
