SG-9101CG-C20SGBAB

Programmable Oscillators Overview

The SG-9101CG-C20SGBAB is a programmable spread spectrum crystal oscillator (XO) manufactured by EPSON. It features a CMOS output and supports frequency programming within the range of 670 kHz to 170 MHz. The device operates on a supply voltage between 1.62V and 3.63V and includes standby functionality. It is housed in a 4-SMD, no-lead package with dimensions of 2.50mm x 2.00mm x 0.80mm. The component supports center-spread mode with an expansion bandwidth of ±2.00% and functions reliably across an operating temperature range of -40°C to 85°C.

Programmable Oscillators Feature Summary

• Supports programmable frequency generation from 670 kHz to 170 MHz via distributor ordering.
• Integrates spread spectrum modulation with center-spread mode for EMI reduction.
• Features low-power standby capability with maximum disabled current of 3.7 mA.
• Utilizes a compact surface-mount 4-SMD lead-free package for space-constrained designs.

Programmable Oscillators Applications

• High-speed serial communication interfaces requiring precise clocking.
• Embedded systems utilizing microcontrollers or FPGAs.
• Consumer electronics devices sensitive to electromagnetic interference.
• Industrial control equipment operating in varying thermal environments.

Programmable Oscillators Procurement Notes

This component is supplied as a blank oscillator and requires specific frequency programming during the ordering process. Customers must input the desired frequency value directly into the order notes when purchasing through authorized distributors such as DigiKey. Verification of the exact programmed frequency is essential prior to integration, as the device ships unprogrammed. Ensure that the selected part number suffix corresponds to the required package and electrical specifications.

Programmable Oscillators Selection Notes

Select this model when a customizable frequency solution within the 670 kHz to 170 MHz range is required. The SG-9101CG series offers flexibility for design variations without changing hardware components. Consider the 4-SMD footprint for PCB layout constraints. Verify that the system power supply remains within the 1.62V to 3.63V operational window. The spread spectrum feature should be evaluated if signal integrity and EMI compliance are critical project requirements.

Programmable Oscillators Part Context

The SG-9101CG-C20SGBAB belongs to the SG-9101Cx series of programmable spread spectrum crystal oscillators. This family provides designers with configurable clock sources that replace fixed-frequency crystals. The series is characterized by its ability to reduce electromagnetic interference through frequency dithering. It serves as a direct replacement for standard XO applications where frequency customization is necessary.

Programmable Oscillators Replacement Considerations

Direct substitutes include other variants within the SG-9101CG series, such as SG-9101CG-C20SGBCA or SG-9101CG-C20SGBAA, which share identical pinouts and functional characteristics. These parts differ primarily in their specific programming configurations or packaging details. Cross-referencing the datasheet is recommended to ensure compatibility with existing board layouts and software configuration tools.
