SG-9101CG-D40SGDCB

Overview

The SG-9101CG-D40SGDCB is a programmable spread spectrum crystal oscillator from the Epson SG-9101CG series. It features a 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 and includes a standby function with a maximum disabled current of 3.7 mA. It utilizes a basic crystal resonator and offers an expansion bandwidth of -4.00% for downward spreading. The component is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm.

Feature Summary

• Supports programmable frequency generation via distributor ordering services
• Integrates downward spread spectrum modulation capability
• Includes low-power standby mode functionality

Applications

• General-purpose clock signal generation for digital circuits
• Embedded systems requiring precise timing references
• Consumer electronics utilizing standard CMOS interfaces

Procurement Notes

This component is typically supplied as a blank oscillator that requires programming by the distributor or manufacturer prior to shipment. Buyers must specify the desired operating frequency during the ordering process. Verify that the specific suffix matches the required frequency and package configuration, as these parameters are not fixed at the time of initial stock holding. Ensure compatibility with the system's voltage and interface requirements before finalizing the purchase order.

Selection Notes

Select this model when a custom frequency within the 670 kHz to 170 MHz range is required without maintaining separate inventory for every possible value. The 4-SMD package suits space-constrained surface-mount designs. Confirm that the CMOS output level aligns with the receiving logic family. The downward spread spectrum feature is beneficial for reducing electromagnetic interference in sensitive applications compared to fixed-frequency alternatives.

Part Context

The SG-9101CG-D40SGDCB belongs to the SG-9101Cx series of programmable oscillators. This series is characterized by its small footprint and wide frequency tunability. Unlike pre-programmed variants, this specific part number represents a configurable unit designed for flexible deployment across various electronic products where standardized clock sources are needed but exact frequencies vary between models.

Replacement Considerations

Direct replacements include other SG-9101CG series variants such as SG-9101CG-D40SGCAC, which shares similar electrical characteristics and packaging. When substituting, ensure the new part supports the required frequency and spread spectrum specifications. Generic oscillators may not offer the same programmability or EMC performance.
