SG-9101CG-D40SHCCA

Overview

The EPSON SG-9101CG-D40SHCCA is a programmable spread spectrum crystal oscillator (XO) featuring a CMOS output interface. It operates within a supply voltage range of 1.62V to 3.63V and supports frequencies from 670 kHz to 170 MHz. The device 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 is designed for an operating temperature range of -40°C to 105°C and incorporates downward frequency spreading.

Feature Summary

• Supports programmable frequency generation across a wide range using standard crystal resonators.
• Incorporates downward spread spectrum modulation to reduce electromagnetic interference.
• Features a low-power standby mode to minimize energy consumption during inactive periods.
• Provides stable CMOS logic outputs suitable for digital system clocking applications.

Applications

• High-speed data communication interfaces requiring precise timing signals
• Embedded systems and microcontroller clock sources
• Industrial control equipment operating in extended temperature environments
• Consumer electronics utilizing spread spectrum techniques for EMI compliance

Procurement Notes

Verify the specific programming requirements before ordering, as this component requires frequency configuration through the distributor's ordering process. Confirm that the 4-SMD package dimensions align with the target PCB layout constraints. Ensure the supply voltage range matches the system design specifications. Check for RoHS3 compliance status if environmental regulations are a strict requirement for the final product assembly.

Selection Notes

Choose this model when a compact, programmable clock source with spread spectrum capabilities is needed. The CMOS output level is suitable for direct interfacing with most digital logic families. Consider the thermal performance and operating temperature range for harsh environment applications. The small footprint makes it ideal for space-constrained designs where traditional oscillators do not fit.

Part Context

This part belongs to the SG-9101CG series of programmable spread spectrum crystal oscillators by Epson. The series is known for offering flexibility in frequency selection while maintaining low jitter and phase noise characteristics. The D40 suffix typically indicates specific spreading parameters, such as the bandwidth and direction of the spread spectrum modulation used in this variant.

Replacement Considerations

Direct replacements may include other SG-9101CG variants with different package sizes or spreading profiles. Verify pin compatibility and electrical specifications when substituting. Ensure the replacement supports the required frequency range and operating temperature. Consult official datasheets for mechanical and electrical equivalence.
