SG-8101CG-TCHPB

Overview

The SG-8101CG-TCHPB is a programmable crystal oscillator manufactured by Epson, housed in a compact 4-SMD, No Lead package with dimensions of 2.50 x 2.00 x 0.80 mm. It operates on a supply voltage range of 1.62V to 3.63V and delivers a CMOS output waveform. The device supports frequencies from 670 kHz to 170 MHz and functions within an operating temperature range of -40°C to +105°C. Key electrical specifications include a maximum current consumption of 8.1 mA at 25°C for higher frequency variants and 3.5 mA for lower frequency options. Frequency tolerance is specified at +/-20 ppm or +/-50 ppm depending on the configuration, with aging included in the first-year tolerance. The component features Enable/Disable functionality for power management.

Feature Summary

• Programmable frequency generation capability covering a wide range from low kilohertz to high megahertz operations
• Integrated enable and disable control function allowing for dynamic power management during operation
• CMOS output interface compatible with standard digital logic circuits requiring minimal external components
• Wide operating temperature range suitable for demanding industrial and commercial electronic environments

Applications

• High-speed data communication interfaces requiring precise clock synchronization
• Portable consumer electronics where low power consumption and small form factor are critical
• Industrial control systems operating in extreme temperature conditions
• Network equipment and routers needing stable timing signals across varying loads

Procurement Notes

Verify the specific frequency and tolerance requirements against the official datasheet before ordering, as parameters vary significantly between sub-models. Confirm the package type matches the PCB footprint design. Ensure the supply voltage range aligns with the target system's power rails. Check for any specific ordering suffixes that may indicate different performance characteristics or packaging options. Cross-reference the part number with the manufacturer's latest documentation to avoid obsolete revisions.

Selection Notes

Select this component when a small surface-mount oscillator with programmable frequency is required. Consider the CMOS output compatibility with the destination logic family. Evaluate the thermal environment to ensure the -40°C to +105°C range meets application needs. Assess the power budget against the maximum current consumption specs. Verify that the enable/disable feature integrates correctly with the system's power sequencing strategy.

Part Context
