Programmable Oscillators Procurement Notes

This component is supplied as a blank oscillator that requires programming at the time of order. Customers must specify the desired frequency in the order notes or through the distributor's ordering interface. Verify that the requested frequency falls within the 670 kHz to 20 MHz operational range. Ensure the supply voltage requirements align with the 1.62V to 3.63V specification before finalizing procurement. Confirm package dimensions match the PCB footprint design.

Programmable Oscillators Selection Notes

Select this model when a small form factor surface-mount oscillator is required for applications needing flexible frequency configuration. The wide operating temperature range makes it suitable for industrial environments. Consider the CMOS output compatibility with the target logic family. The spread spectrum feature should be evaluated if EMI compliance is a critical design constraint. Verify that the standby current meets the system's power budget constraints.

Programmable Oscillators Part Context

The SG-9101CG series represents EPSON's line of programmable spread spectrum crystal oscillators. This specific part number denotes the CG variant with standard XO output and CMOS interface. The series is designed to replace fixed-frequency crystals and oscillators, offering design flexibility. It is part of EPSON's broader portfolio of timing solutions aimed at reducing electromagnetic interference in high-speed digital circuits.

Programmable Oscillators Replacement Considerations

Direct replacements are limited due to the programmable nature of the component. Similar models in the SG-9101CG series may offer different frequency ranges or package options but require separate programming. Fixed-frequency oscillators cannot directly substitute this part without redesigning the clock distribution network. Consult EPSON documentation for cross-reference data regarding alternative programmable devices.

Programmable Oscillators FAQ

How is the output frequency determined for this component?

The frequency is not pre-set; it is programmed by the manufacturer based on the specific value entered by the customer in the order notes or ordering system.

What is the function of the standby pin?

The standby function allows the oscillator to enter a low-power state, reducing the supply current to a maximum of 3.7 mA when disabled.
