SG-8018CB-TJHPB

Overview

The EPSON SG-8018CB-TJHPB is a programmable crystal oscillator (XO) featuring CMOS output. It operates within a supply voltage range of 1.8V to 3.3V and supports frequencies from 670 kHz to 170 MHz. The device offers frequency stability of ±50 ppm across an operating temperature range of -40°C to +105°C. Maximum supply current is 3.5 mA, with enable/disable functionality available. It utilizes a 4-SMD, no-lead package measuring 5.00mm x 3.20mm x 1.30mm maximum height.

Feature Summary

• Programmable frequency generation capability for customized clock requirements
• Integrated enable and disable control function for power management
• Wide operating voltage compatibility supporting 1.8V to 3.3V systems
• Industrial temperature rating ensuring reliability in harsh environments

Applications

• High-speed data communication interfaces requiring precise timing
• Embedded systems needing customizable clock frequencies
• Industrial control equipment operating in extreme temperatures
• Consumer electronics demanding low power consumption modes

Procurement Notes

This component requires specific programming for the desired output frequency during order placement. Verify that the requested frequency falls within the 670 kHz to 170 MHz range. Confirm voltage and package specifications match the target design. Ensure compliance with RoHS3 standards if required by project regulations. Check availability as lead times may vary based on programming requirements.

Selection Notes

Select this model when a flexible, programmable clock source is needed rather than a fixed-frequency oscillator. Consider the 4-SMD package size constraints and verify that the 1.8V-3.3V supply range aligns with the system power architecture. Evaluate the ±50 ppm stability requirement against system jitter tolerance. Ensure the enable/disable feature integrates correctly with the host controller's GPIO capabilities.

Part Context

The SG-8018CB-TJHPB belongs to Epson's SG-8018CB series of programmable crystal oscillators. This series provides a compact solution for applications requiring specific clock frequencies not available in standard off-the-shelf parts. It complements other variants in the family that may offer different packages or fixed frequencies, providing design flexibility for engineers.

Replacement Considerations

Direct substitutes include other SG-8018CB series variants with compatible packages and electrical characteristics. Verify pinout compatibility and voltage levels before substitution. Alternative programmable oscillators from other manufacturers may require firmware adjustments. Fixed-frequency equivalents are only suitable if the specific programmed frequency matches the application needs exactly.
