SSX-750PTB

Overview

The SSX-750PTB is a programmable crystal oscillator manufactured by Citizen Finedevice Co Ltd. It operates within a frequency range of 1 MHz to 125 MHz and utilizes TTL logic levels with a standard supply voltage of 5V. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead surface-mount package suitable for automated assembly. The component supports an operating temperature range of -20°C to 70°C and maintains a frequency stability of ±50ppm.

Feature Summary

• Programmable frequency generation capability across a wide range
• Integrated enable/disable pin for standby power control
• TTL-compatible output logic levels
• Surface-mount design for space-constrained applications

Applications

• Digital signal processing systems requiring precise clock sources
• Communication equipment utilizing standard TTL interfaces
• Industrial control systems needing stable timing references
• Consumer electronics with limited board space requirements

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct logic family and tolerance specifications. Confirm that the 4-SMD package variant matches your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the enable pin configuration aligns with your system's power sequencing needs before finalizing procurement orders.

Selection Notes

Select this component when a fixed-frequency oscillator does not meet system timing requirements. The programmable nature allows customization of the output frequency within the specified range. Consider the ±50ppm stability requirement against your system's jitter tolerance. The 5V supply voltage must match your existing logic domain to avoid level shifting issues. Evaluate the thermal performance within the -20°C to 70°C range for your specific environment.

Part Context

This part belongs to the SSX-750P series of programmable oscillators from Citizen Finedevice. The series offers various logic families and stability options. The PTB suffix typically denotes specific electrical characteristics and packaging details. This series is designed for general-purpose timing applications where flexibility in frequency selection is necessary without sacrificing reliability.

Replacement Considerations

Direct substitutes may include other parts from the SSX-750P series with compatible logic levels. Verify pinout compatibility before swapping components. Alternative manufacturers may offer similar programmable oscillators but require careful verification of electrical parameters and package dimensions to ensure functional equivalence.
