SG-8018CB-TJHPA

Overview

The SG-8018CB-TJHPA is a standard clock oscillator from the Epson SG-8018 series. It operates at frequencies such as 19.2 MHz, 27.428571 MHz, and 39.0625 MHz. The device supports supply voltages of 1.8V, 2.5V, or 3.3V with CMOS output levels. Frequency stability is maintained within +/-50 ppm across an operating temperature range of -40°C to +105°C. The component is housed in a 4-pin SMD package (5032-4P) and is available in cut tape, reel, or MouseReel packaging formats.

Feature Summary

• Supports multiple supply voltage options including 1.8V, 2.5V, and 3.3V for flexible system integration.
• Provides stable frequency generation with +/-50 ppm accuracy over a wide industrial temperature range.
• Features a compact surface-mount design suitable for space-constrained electronic applications.

Applications

• Industrial control systems requiring reliable timing signals
• Communication equipment utilizing standard clock frequencies

Procurement Notes

Verify the specific frequency suffix (e.g., 19.2000M, 27.428571M) when ordering, as the base model number represents a family. Confirm the required supply voltage and output load capacitance match your circuit design. Ensure the selected packaging format (cut tape or reel) aligns with your assembly line capabilities. Cross-reference the manufacturer part number with distributor codes to avoid selection errors.

Selection Notes

Select this oscillator based on the required operating frequency and environmental temperature constraints. The +/-50 ppm tolerance suits general-purpose digital logic and communication interfaces. Consider the 5032-4P footprint dimensions during PCB layout. Verify that the chosen voltage level matches the target system's power rails to ensure proper signal integrity and power consumption.

Part Context

This component belongs to the SG-8018 series of pre-programmed crystal oscillators manufactured by Epson Timing. The series is designed for high reliability and low phase noise. The CB variant typically denotes specific electrical characteristics within the broader product line. These oscillators are widely used in applications demanding stable clock sources under varying thermal conditions.

Replacement Considerations

Direct substitutes include other SG-8018 series variants with matching frequency and package. Check datasheets for pin compatibility and voltage tolerances before swapping. Generic replacements may not offer identical temperature stability or phase noise performance.
