581R500X2ITT

Oscillators Overview

The 581R500X2ITT is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 50 MHz and utilizes HCMOS output logic. The device is designed for surface-mount assembly in an 8-SMD, No Lead package. It functions within a supply voltage range of 3V to 3.6V. The component supports operation across an extended temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Integrates temperature compensation circuitry to maintain frequency stability across varying thermal conditions.
• Provides single-ended HCMOS digital output signals suitable for direct interfacing with standard logic circuits.
• Utilizes a compact surface-mount package design optimized for automated PCB assembly processes.

Oscillators Applications

• Wireless infrastructure equipment requiring precise timing references
• Wireline core networking systems
• Test and measurement instrumentation

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout configuration, tolerance class, and packaging type. Ensure the selected variant matches the required load capacitance and drive level specifications for the target application circuit. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing standards.

Oscillators Selection Notes

Select this component when a stable 50 MHz reference signal is required in space-constrained designs. Evaluate the trade-off between the TCXO's improved stability over standard XO types and its higher cost. Confirm that the 8-pin form factor fits the available footprint and that the HCMOS output swing aligns with the receiving device's input thresholds.

Oscillators Part Context

This oscillator belongs to the 581 series of clock oscillators from CTS-Frequency Controls. The series offers various frequencies and output types, including LVPECL and LVDS, to support diverse timing needs in high-performance electronic systems. The 581 series is engineered for reliability in demanding environments.

Oscillators Replacement Considerations

Consult the official CTS substitution guide for verified equivalents. Direct replacements must match the 50 MHz frequency, 8-SMD package, and HCMOS output characteristics. Verify that any substitute part maintains identical electrical parameters and thermal performance ratings.
