SG-9101CG-D40PHAAB

Overview

The SG-9101CG-D40PHAAB is a programmable spread spectrum crystal oscillator (XO) manufactured by EPSON. It features a CMOS output and supports frequencies ranging from 670 kHz to 170 MHz. The device operates on a supply voltage of 1.62V to 3.63V and includes an enable/disable function for power management. It utilizes downward spread spectrum modulation 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 operation within a temperature range of -40°C to +105°C.

Feature Summary

• Supports programmable frequency generation across a wide range using internal crystal resonators.
• Integrates downward spread spectrum modulation to reduce electromagnetic interference (EMI).
• Includes an enable/disable control pin for active power management and standby modes.

Applications

• High-speed digital signal processing systems requiring precise clocking.
• Communication equipment needing EMI reduction through spread spectrum techniques.
• Portable electronic devices utilizing low-voltage CMOS logic interfaces.

Procurement Notes

This specific part number represents a standard configuration within the SG-9101 series. When ordering, verify that the suffix matches the required package type and functional specifications. Ensure that the requested frequency falls within the supported 670 kHz to 170 MHz range. Confirm that the supply voltage requirements align with the 1.62V to 3.63V operational limits. Check for any specific programming instructions if custom frequencies are needed beyond standard catalog values.

Selection Notes

Select this component when EMI mitigation is critical for system compliance. The downward spread spectrum feature helps minimize peak noise emissions. The CMOS output ensures compatibility with standard digital logic families. Verify thermal requirements against the -40°C to +105°C operating range. Consider the small 4-SMD footprint for space-constrained PCB layouts.

Part Context

The SG-9101 series comprises programmable spread spectrum crystal oscillators designed for high-performance applications. This model belongs to the CG variant, indicating specific package and environmental characteristics. The series is known for combining low jitter performance with EMI reduction capabilities. It serves as a direct replacement for fixed-frequency oscillators where flexibility and noise management are priorities.

Replacement Considerations

Direct substitutes include other SG-9101CG variants with compatible pinouts and electrical parameters. Verify that alternative models support the same 4-SMD 2.5x2 package dimensions. Ensure the replacement maintains the CMOS output type and 1.62V-3.63V supply range. Check if the substitute offers similar spread spectrum bandwidth specifications.
