SG-9101CG-D30SGDAB

Overview

The SG-9101CG-D30SGDAB is a programmable spread spectrum crystal oscillator (XO) manufactured by EPSON. It features a CMOS output and operates within a supply voltage range of 1.62V to 3.63V. The device supports a frequency range from 670 kHz to 170 MHz and includes a standby function with a maximum disabled current of 3.7 mA. It utilizes a 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm. The unit offers a spectrum bandwidth of -3.00% down spread and functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Supports programmable frequency generation within the specified range via distributor ordering process
• Integrates spread spectrum modulation with downward frequency deviation for EMI reduction
• Includes low-power standby mode to minimize energy consumption during inactivity

Applications

• High-speed digital signal processing systems requiring precise clock synchronization
• Communication equipment utilizing spread spectrum techniques to mitigate electromagnetic interference
• Embedded computing platforms operating within standard industrial temperature ranges

Procurement Notes

This component is supplied as a blank oscillator that requires frequency programming. Customers must specify the desired operating frequency directly in the order notes when purchasing through authorized distributors such as DigiKey. The device is not pre-programmed at the factory; therefore, accurate communication of the target frequency during the procurement phase is essential to ensure the delivered unit meets specific system timing requirements.

Selection Notes

Engineers should verify that the required operating frequency falls within the 670 kHz to 170 MHz range before selecting this part. The design must accommodate the 1.62V to 3.63V supply voltage constraints and ensure compatibility with CMOS logic levels. Additionally, thermal management strategies should account for the -40°C to 85°C operational envelope to maintain performance stability under varying environmental conditions.

Part Context

This model belongs to the SG-9101CG series of programmable spread spectrum crystal oscillators. The series is designed for applications demanding flexible clock frequencies and reduced electromagnetic emissions. The specific suffix indicates the package type, voltage range, and spread spectrum characteristics, distinguishing it from other variants in the EPSON portfolio that may offer different form factors or modulation profiles.

Replacement Considerations

Direct substitutes include other SG-9101CG variants with compatible packages and electrical specifications, such as SG-9101CG-D30SGCCA or SG-9101CG-D30SGDCB. When replacing, ensure the new part supports the same programmable frequency range and spread spectrum bandwidth. Verify that the replacement maintains the 4-SMD no-lead footprint and CMOS output compatibility.
