SG-9101CG-D40PGBAB

Overview

The SG-9101CG-D40PGBAB is a programmable spread spectrum crystal oscillator from the Epson SG-9101 series. It features a CMOS output and operates within a supply voltage range of 1.62V to 3.63V. The device supports frequencies from 670 kHz to 170 MHz and includes an enable/disable function for power management. It utilizes a down-spread modulation profile with a bandwidth of -4.00%. The component is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm. It is designed for surface-mount installation and functions across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Programmable frequency generation with integrated spread spectrum modulation capability
• Low standby current consumption enabled by dedicated control pin functionality
• Compact surface-mount footprint suitable for high-density PCB layouts

Applications

• High-speed serial communication interfaces requiring jitter reduction
• Embedded systems with strict electromagnetic interference constraints

Procurement Notes

Verify that the specific suffix D40PG corresponds to the required down-spread modulation profile and frequency range during procurement. Confirm the enable/disable pin configuration matches the system design requirements. Ensure the operating voltage aligns with the 1.62V to 3.63V specification. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate the package dimensions against the PCB footprint library before ordering.

Selection Notes

Select this component when spread spectrum clocking is necessary to minimize EMI emissions in digital circuits. Consider the available programming options provided by the manufacturer for custom frequency settings. Evaluate the trade-off between the wide frequency range and the specific modulation characteristics required. Assess the thermal performance within the specified industrial temperature limits. Compare the package size against other oscillators in the same series for space optimization.

Part Context

This part belongs to the SG-9101 series of programmable crystal oscillators manufactured by Epson. The series offers various output types and packaging options to suit different application needs. The SG-9101CG variant specifically denotes the CMOS output type and the particular package style. Other members of the family may differ in output drive strength, voltage range, or modulation profiles while sharing similar core technologies.

Replacement Considerations

Direct substitutes include other SG-9101 series parts with matching package and electrical specifications. Verify that alternative models support the same -4.00% down-spread modulation requirement. Ensure replacement components maintain compatibility with the 1.62V to 3.63V supply range. Check that the substitute part offers the same enable/disable functionality for power management.
