SG-9101CE-D20SGBAB

Programmable Oscillators Overview

The SG-9101CE-D20SGBAB is a programmable spread spectrum crystal oscillator from Epson, designed for standard XO applications with CMOS output. It operates within a frequency range of 670 kHz to 170 MHz and supports supply voltages between 1.62V and 3.63V. The device features a downward spread spectrum bandwidth of -2.00% and includes a standby function with a maximum disabled current of 3.7 mA. It is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm, suitable for surface mount installation across an operating temperature range of -40°C to 85°C.

Programmable Oscillators Feature Summary

• Programmable frequency generation within the specified range via distributor ordering notes

Programmable Oscillators Procurement Notes

This component is supplied as a blank oscillator that requires programming by the distributor prior to shipment. Customers must specify the desired frequency in the order remarks when purchasing through authorized channels such as DigiKey. Lead times may apply as the unit is programmed after the order is placed. Verify that the specific model suffix corresponds to the required spread spectrum type and voltage range before finalizing procurement documentation.

Programmable Oscillators Selection Notes

Select this part when a precise CMOS clock signal with downward spread spectrum characteristics is required. Ensure the system voltage falls within the 1.62V to 3.63V operational window. Confirm that the 4-SMD footprint fits the PCB layout constraints. This model is distinct from center-spread variants; verify the 'D' suffix indicates downward spread if EMI mitigation direction is critical to the design.

Programmable Oscillators Part Context

The SG-9101 series represents Epson's line of programmable spread spectrum crystal oscillators. These devices integrate a crystal resonator with control circuitry to provide stable clock outputs. The SG-9101CE variant specifically denotes the package style and electrical characteristics within this family, offering flexibility in frequency selection while maintaining small form factor requirements for modern electronics.

Programmable Oscillators Replacement Considerations

Direct substitutes include other SG-9101CG or SG-9101CE models with matching spread spectrum types (downward) and compatible voltage ranges. Cross-model replacement requires verification of pinout compatibility and package dimensions. Generic oscillators cannot replace this programmable unit without external configuration circuitry.
