Procurement Notes
Verify that the specific suffix PGCAA corresponds to the required frequency programming method and package variant. Confirm that the order specifies the exact target frequency within the 670 kHz to 170 MHz range, as this is a programmable device. Ensure compatibility with the 1.62V to 3.63V supply voltage requirements of the target circuit. Check for RoHS3 compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this model when flexible frequency configuration is needed without maintaining multiple stock variants. The CMOS output level is suitable for direct interfacing with digital logic circuits. Consider the 4-SMD footprint for PCB layout constraints. Evaluate the need for spread spectrum functionality to meet electromagnetic interference standards in sensitive environments compared to fixed-frequency alternatives.
Part Context
This component belongs to the SG-9101 series of programmable spread spectrum crystal oscillators manufactured by EPSON. The series is designed to replace fixed-frequency oscillators in designs requiring frequency agility. The SG-9101CG-D40PGCAA specifically denotes the CMOS output type and downward spread spectrum feature. It is part of Epson's portfolio aimed at reducing electromagnetic interference in high-density electronic systems.
Replacement Considerations
Direct substitutes include other SG-9101CG variants with compatible packages and electrical characteristics. Verify pinout compatibility before swapping. Models like SG-9101CG-D40SGCAC offer similar programmability but may differ in specific packaging or ordering procedures. Ensure the replacement maintains the same CMOS output drive strength and voltage range.
