SG-9101CG-D40PHDAC

Overview

The SG-9101CG-D40PHDAC is a programmable spread spectrum crystal oscillator manufactured by EPSON. It operates within a frequency range of 670 kHz to 20 MHz and supports CMOS output signals. The device functions on a supply voltage between 1.62V and 3.63V and features enable/disable control capabilities. It utilizes a 4-SMD, no lead package with dimensions of 2.50mm x 2.00mm x 0.80mm. The component is designed for operation across a temperature range of -40°C to 105°C and incorporates downward spread spectrum modulation with a bandwidth of -4.00%.

Feature Summary

• Supports programmable frequency generation within the specified range via external configuration.
• Integrates downward spread spectrum modulation to reduce electromagnetic interference.
• Features low power consumption with dedicated enable and disable control pins.

Applications

• High-speed digital signal processing systems
• Communication equipment requiring clock synchronization
• Embedded systems with strict EMI constraints

Procurement Notes

Verify the specific frequency requirement during procurement as this model requires programming. Confirm that the ordering process includes the necessary frequency specification input. Ensure compatibility with the 1.62V to 3.63V supply voltage range. Check for RoHS3 compliance status if environmental regulations apply. Validate the 4-SMD package footprint against the target PCB design.

Selection Notes

Select this component when a programmable clock source with spread spectrum capabilities is required. Consider the CMOS output level and the -40°C to 105°C operating temperature range. Evaluate the need for enable/disable functionality for power management. Compare the 2.50mm x 2.00mm package size against available board space. Assess the frequency stability requirements against the programmable nature of the device.

Part Context

This part belongs to the SG-9101Cx series of programmable spread spectrum crystal oscillators. The series is characterized by its compact surface-mount package and flexible frequency programming options. It is designed to replace fixed-frequency crystals in applications where jitter reduction and EMI suppression are critical.
