SG-8101CE 19.9500M-TCHSA0

Oscillators Overview

The SG-8101CE 19.9500M-TCHSA0 is a standard CMOS clock oscillator from Epson's SG-8101 series, operating at a fixed frequency of 19.95 MHz. It supports a supply voltage range of 1.8V to 3.3V and features a ±20ppm frequency stability across an industrial temperature range of -40°C to +105°C. The device includes a standby function for power management and is housed in a compact 4-SMD, no-lead package with a maximum seated height of 1.20mm.

Oscillators Feature Summary

• CMOS output interface compatible with standard digital logic levels
• Integrated standby mode for active power-down control
• Industrial-grade temperature rating for harsh environments

Oscillators Applications

• High-speed data communication interfaces
• Microprocessor and microcontroller clock sources
• Network equipment timing circuits

Oscillators Procurement Notes

Verify the specific suffix TCHSA0 against official Epson documentation to confirm the exact frequency tolerance and packaging configuration. Ensure the procurement channel provides valid RoHS compliance certificates matching the component specifications. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Oscillators Selection Notes

Select this model when a precise 19.95 MHz reference is required with low power consumption. Consider the 4-SMD package for space-constrained PCB layouts. Evaluate the ±20ppm stability against system jitter requirements. Confirm that the 1.8V to 3.3V supply range aligns with the target circuit design.

Oscillators Part Context

This component belongs to the SG-8101 programmable crystal oscillator family, which offers various frequency options within a standardized footprint. The SG-8101CE variant specifically denotes the CMOS output type and operational characteristics. It serves as a direct replacement for legacy discrete crystal solutions requiring integrated oscillator functionality.

Oscillators Replacement Considerations

Direct substitutes include other SG-8101CE variants with identical pinouts but different frequencies, such as SG-8101CE 19.9340M-TCHSA0 or SG-8101CE 19.9400M-TCHSA0, provided the frequency difference is acceptable for the application.
