Overview
The SG-9101CG-D40PGBAA is a programmable spread spectrum crystal oscillator (XO) manufactured by EPSON. It features CMOS output and supports a frequency range of 670 kHz to 170 MHz. The device operates on a supply voltage of 1.62V to 3.63V and includes an enable/disable function. It utilizes a down spread modulation with a bandwidth of -4.00%. The component is housed in a 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm. It functions within a temperature range of -40°C to 85°C.
Feature Summary
- Programmable frequency generation within the specified wide range
- Down spread modulation capability for EMI reduction
- Low power consumption with standby functionality
- Compact surface-mount design suitable for space-constrained applications
Applications
- General purpose clock sources for digital circuits
- Embedded systems requiring precise timing
- Consumer electronics with EMI sensitivity
- Industrial control boards
Procurement Notes
Verify the exact operating frequency required during ordering, as this model is programmable. Confirm that the application environment stays within the specified voltage and temperature limits. Ensure compatibility with the CMOS logic levels used in the target circuit. Check RoHS compliance status if environmental regulations apply to the final product assembly.
Selection Notes
Choose this component when a specific frequency outside standard fixed values is needed. Consider the 4-SMD package size for PCB layout constraints. Evaluate the need for spread spectrum functionality to meet electromagnetic interference standards. Compare power requirements against available supply rails to ensure stable operation across the full voltage range.
Part Context
This part belongs to the SG-9101Cx series of programmable spread spectrum crystal oscillators. The series offers flexibility in frequency selection while maintaining low jitter performance. The SG-9101CG variant specifically denotes the commercial grade temperature range and package type. It serves as a versatile clock source replacing multiple fixed-frequency oscillators.
Replacement Considerations
Direct substitutes include other SG-9101CG variants with different suffixes such as SG-9101CG-D40PHBAA or SG-9101CG-D40PGACC, provided they match the required frequency and pinout. Verify package dimensions and electrical characteristics before swapping.
