Overview
The SG-9101CG-D40SGCCB is a programmable spread spectrum crystal oscillator from Epson. It features CMOS output and operates within a supply voltage range of 1.62V to 3.63V. The device supports a frequency range of 670 kHz to 170 MHz with downward spread spectrum modulation of -4.00%. It includes a standby function with a maximum disabled current of 3.7 mA. The component is housed in a 4-SMD, no lead package measuring 2.50mm x 2.00mm x 0.80mm. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Programmable frequency generation within the specified range
- Downward spread spectrum modulation capability for EMI reduction
- Integrated standby mode for power management
Applications
- High-speed digital signal processing systems
- Communication equipment requiring low jitter clocks
- Embedded computing platforms
Procurement Notes
Verify the specific frequency requirement during ordering as this model is programmable. Confirm that the downstream circuitry supports the 1.62V to 3.63V supply range and CMOS logic levels. Ensure the PCB footprint matches the 4-SMD no-lead dimensions of 2.50mm by 2.00mm. Check compatibility with the -40°C to +85°C industrial temperature rating for the intended application environment.
Selection Notes
Select this component when a precise, programmable clock source with spread spectrum capabilities is required. It is suitable for designs needing flexible frequency adjustment post-production. Consider the small surface-mount package size for space-constrained layouts. Evaluate the standby current consumption if power efficiency in idle states is a critical design parameter.
Part Context
This part belongs to the SG-9101CG series of programmable oscillators by Epson. The series is designed for applications demanding high stability and low phase noise. The SG-9101CG-D40SGCCB specifically denotes the variant with downward spread spectrum functionality and standard CMOS output. It represents a solution for modern electronics requiring adaptable clocking architectures.
Replacement Considerations
Consult official Epson documentation for direct cross-reference substitutes. Verify pinout compatibility and electrical specifications before considering alternative manufacturers. Ensure any replacement maintains the same package dimensions and operating temperature range.
