SG-8003CA-SEC

Overview

The SG-8003CA-SEC is a programmable CMOS clock oscillator manufactured by EPSON. It operates within a frequency range of 1MHz to 166MHz with a nominal stability of ±100ppm. The device supports a supply voltage of 2.5V and features a standby function for power management. It is housed in a 4-SMD, no-lead ceramic package measuring 7.00mm x 5.00mm x 1.40mm. The unit functions reliably across an operating temperature range of -20°C to +70°C.

Feature Summary

• Programmable frequency generation capability allowing customization between 1MHz and 166MHz
• Integrated standby mode to reduce power consumption during inactive periods
• CMOS output interface compatible with standard digital logic circuits

Applications

• Embedded systems requiring precise timing references
• Consumer electronics utilizing programmable clock sources
• Industrial control equipment needing stable signal generation

Procurement Notes

Verify the specific frequency order code when placing orders, as this component requires programming. Confirm that the 2.5V supply voltage aligns with system requirements. Ensure the 7050 package dimensions fit the designated PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Choose this model when a fixed-frequency crystal is insufficient for design flexibility. The ±100ppm stability suits general-purpose applications rather than high-precision radio systems. Consider the 2.5V operation if lower voltage rails are available compared to 3.3V alternatives. The standby feature is advantageous for battery-powered devices requiring extended operational life.

Part Context

This part belongs to the SG-8003CA series of programmable surface-mount oscillators from EPSON. It shares the 7050 physical form factor with other variants like the SG-8003CA-PCL but differs in electrical specifications and programming requirements. The series provides a scalable solution for manufacturers needing customized frequencies without redesigning hardware layouts.

Replacement Considerations

Direct substitutes include other SG-8003CA variants such as SG-8003CA-PCL or SG-8003CA-SDC, provided they match the required frequency and voltage. Verify pin compatibility and package dimensions before swapping. Note that replacement units may require separate frequency programming services.
