SSX-750PKB

Overview

The SSX-750PKB 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 a base crystal resonator. The device features TTL output levels with a supply voltage of 5V and supports a standby mode for power management. It is housed in a compact 4-SMD, no lead surface-mount package. The unit maintains a frequency stability of ±50 ppm.

Feature Summary

• Programmable frequency generation capability
• Integrated standby power-down mode
• TTL-compatible output interface

Applications

• Embedded communication systems
• General-purpose timing circuits
• Digital signal processing interfaces

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the component matches the required frequency tolerance and package dimensions for your design. Cross-reference the part number with authorized distributors to confirm authenticity and avoid counterfeit components during acquisition.

Selection Notes

Select this model when a 5V TTL output is required alongside programmable frequency control. Consider the ±50 ppm stability requirement against system timing constraints. Evaluate the 4-SMD footprint availability on the PCB layout. Compare performance against alternative series members if different voltage levels or package styles are necessary for the application.

Part Context

This component belongs to the SSX-750 series of programmable oscillators from Citizen Finedevice. The series offers various configurations differing by output logic, supply voltage, and frequency stability. The PKB suffix specifically denotes the 5V TTL variant with 50 ppm stability, distinguishing it from CMOS or higher-stability options within the same product family.

Replacement Considerations

SSX-750PBF serves as a comparable alternative within the series, offering similar programmable functionality but with CMOS outputs and a 3.3V supply voltage. Verify that the target circuit supports the voltage level difference before substitution.
