18QHTF21-119.000-PD

Overview

The 18QHTF21-119.000-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 119.0 MHz with LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function. It is housed in a 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Generates a stable 119 MHz clock signal using standard crystal oscillator technology.
• Features LVCMOS output logic for digital interface compatibility.
• Includes a standby mode to reduce power consumption when not in use.

Applications

• Digital signal processing systems requiring precise timing
• Communication equipment utilizing 119 MHz reference frequencies
• Embedded systems with 1.8V logic level requirements

Procurement Notes

Verify the specific order suffix '-PD' confirms the power-down feature and 1.8V operation as documented. Ensure the 4-SMD no-lead package footprint matches the target PCB design. Confirm that the manufacturer is Mercury Electronics Ind. Co. Ltd to avoid counterfeit components from other entities using similar naming conventions.

Selection Notes

Select this component when a fixed 119 MHz frequency is required with low voltage operation. The 1.8V supply requirement limits compatibility to 1.8V logic domains. The small 2.0x1.6 mm package is suitable for space-constrained designs. Verify that the LVCMOS output swing meets the input thresholds of the receiving circuitry.

Part Context

This part belongs to the Mercury Electronic Ind. Co. Ltd XO series, characterized by SMD packaging and specific voltage ratings. Similar models in the series include variants with different frequencies such as 51.2 MHz or 80 MHz, sharing the same physical footprint and logical interface standards.

Replacement Considerations

Direct substitutes must match the 119 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering pin-compatible oscillators with identical electrical specifications to ensure functional equivalence without redesign.

FAQ

Does the 18QHTF21-119.000-PD support spread spectrum functionality?

Available datasheets describe it as a standard XO with LVCMOS output and standby features. Spread spectrum capability is not explicitly confirmed in the provided public documentation.

What is the operating temperature range for this oscillator?

The provided source material does not specify the operating temperature range. This parameter must be verified from the official manufacturer datasheet before implementation.
