18QHTF21-119.000-OE

Overview

The 18QHTF21-119.000-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 119.0 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a 1.8V supply voltage. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This surface-mount oscillator provides precise timing signals suitable for digital circuits requiring stable clock sources.

Feature Summary

• Produces a stable 119.0 MHz clock signal using LVCMOS output logic
• Operates on a single 1.8V power supply rail
• Includes hardware enable and disable functionality for power management
• Utilizes a small footprint 4-SMD no-lead surface mount package

Applications

• Digital system clock generation
• Data communication interface timing
• Embedded processor clock sources
• Consumer electronics timing circuits

Procurement Notes

Verify the specific suffix (OE) against the manufacturer's current datasheet to confirm pinout configuration and electrical tolerances. Ensure the required operating temperature range aligns with the application environment. Confirm that the 1.8V supply voltage matches the target system design before procurement.

Selection Notes

Select this component when a low-voltage 119 MHz clock source is required in a minimal space-constrained design. The LVCMOS output is compatible with standard CMOS logic families. Consider the enable pin requirement if dynamic power saving is necessary for the end product.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 119.0 MHz variant provides a specific high-frequency solution within the standard LVCMOS family, distinct from differential or higher voltage variants.

Replacement Considerations

Direct substitutes include other 119 MHz LVCMOS oscillators in 2.0x1.6mm packages from Mercury Electronics, such as the 18QHTF21-119.000-PD, provided pin compatibility and voltage levels are verified.
