TP53A-L25CQ33T2-312.500M-TR

Oscillators Overview

The TP53A-L25CQ33T2-312.500M-TR is a standard crystal oscillator (XO) manufactured by Transko Electronics, Inc., operating at a frequency of 312.5 MHz. It utilizes Low-Voltage Differential Signaling (LVDS) output and functions on a 3.3V supply voltage. The device features an enable/disable control function and is housed in a compact 6-SMD, No Lead package. It draws up to 45mA current and requires low-impedance power delivery to maintain signal integrity.

Oscillators Feature Summary

• Generates a precise 312.5 MHz clock signal using LVDS technology for high-speed data transmission.
• Incorporates an enable/disable pin allowing for active power management and system control.
• Designed with a lead-free, RoHS-compliant surface-mount package for automated assembly.

Oscillators Applications

• High-speed serial communication interfaces requiring differential signaling
• Network infrastructure equipment and telecommunications systems
• Data acquisition systems needing stable clock sources

Oscillators Procurement Notes

Verify the specific part number suffixes against official Transko Electronics documentation to ensure compatibility with your design requirements. Confirm that the 3.3V supply rail can provide sufficient current without excessive impedance to preserve LVDS signal quality. Ensure the PCB layout supports the 6-SMD no-lead package dimensions and thermal specifications outlined in the manufacturer's datasheet.

Oscillators Selection Notes

Select this component when a 312.5 MHz clock source with LVDS outputs is required for noise immunity. The integrated enable/disable feature makes it suitable for power-sensitive applications. Ensure the system design accommodates the 45mA current draw and provides a stable 3.3V supply. This model is appropriate for designs prioritizing signal integrity over single-ended alternatives.

Oscillators Part Context

This oscillator belongs to the TP53A series from Transko Electronics, which offers various frequencies and voltage options. The 'L25' designation typically relates to the series configuration, while 'CQ33' indicates the 3.3V supply variant. The '-312.500M-' specifies the exact oscillation frequency, distinguishing it from other models in the same physical package family.

Oscillators Replacement Considerations

The TP53A-L25CQ25T2-312.500M-TR serves as a functional substitute but operates on a 2.5V supply instead of 3.3V. Verify voltage compatibility before substitution. Other frequency variants within the TP53A series may share the package but differ electrically.

Oscillators FAQ

How should the enable/disable pin be handled if not used?

The control pin must be tied to a defined logic state and should not be left floating to ensure proper operation.

What are the power supply requirements for this oscillator?

It requires a 3.3V supply and draws up to 45mA, necessitating low-impedance power delivery to maintain LVDS signal integrity.
