SG-8018CG-TJHPB

Overview

The SG-8018CG-TJHPB is a programmable crystal oscillator from Epson Timing, designed for high-frequency precision applications. It operates within a frequency range of 670 kHz to 170 MHz, offering flexibility for non-standard clock requirements. The device supports supply voltages between 1.8 V and 3.3 V, ensuring compatibility with various digital logic families. It features CMOS output format and maintains a frequency stability of ±50 ppm across the operating temperature range of -40°C to +105°C. The component is housed in a compact 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm, suitable for space-constrained surface-mount designs.

Feature Summary

• Fully programmable frequency generation capability covering a wide spectrum from kilohertz to megahertz ranges
• Integrated enable/disable control function for power management and system synchronization
• Robust industrial-grade temperature rating supporting extreme environmental conditions

Applications

• High-speed data communication interfaces requiring precise clock signals
• Embedded systems and microcontrollers needing custom frequency configurations
• Industrial automation equipment operating in harsh thermal environments

Procurement Notes

This component is manufactured as a blank programmable unit. Customers must specify the desired target frequency during the ordering process, typically through order remarks or dedicated programming services provided by distributors. Verify that the required frequency falls within the supported operational range of 670 kHz to 170 MHz before placing orders to ensure successful programming and functional compliance.

Selection Notes

Select this model when standard fixed-frequency oscillators do not meet specific timing requirements. It is ideal for designs necessitating unique clock speeds without custom mask programming. Ensure the application voltage aligns with the 1.8 V to 3.3 V support window. Consider the ±50 ppm stability specification against system jitter tolerance requirements. The compact SMD footprint aids in dense PCB layout strategies.

Part Context

The SG-8018CG-TJHPB belongs to the SG-8018CG series of programmable crystal oscillators. This series distinguishes itself from fixed-frequency counterparts by allowing post-manufacturing frequency configuration. It shares the same physical dimensions and electrical interface characteristics as other members of the family, facilitating design-in flexibility while maintaining consistent performance metrics across the product line.

Replacement Considerations

Direct replacements are limited due to the programmable nature of this specific part number. Fixed-frequency equivalents from the SG-8018CG series may serve as substitutes if the application can accommodate a standard frequency. Verify pinout compatibility and voltage levels when considering alternative programmable models from other manufacturers.
