18QHTF21-58.934167-OE

Overview

The 18QHTF21-58.934167-OE is a fixed-frequency crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 58.934167 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for standard clock signal generation applications requiring precise timing stability.

Feature Summary

• Supports Enable/Disable functionality for dynamic power control
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact 4-SMD no-lead surface mount package design

Applications

• Digital clock signal distribution
• Microprocessor timing references
• Communication interface synchronization

Procurement Notes

Verify the specific suffix 'OE' corresponds to the required Enable/Disable pin configuration during procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 2.0x1.6mm footprint matches the PCB land pattern. Cross-reference the part number with official Mercury Electronics documentation to confirm availability and lead times before finalizing orders.

Selection Notes

Select this component when a 58.934167 MHz clock source is required with low-voltage operation. The LVCMOS output ensures compatibility with standard digital logic families. The enable/disable feature allows for system-level power optimization. Consider the small form factor for space-constrained designs. Verify temperature range requirements against the datasheet specifications.

Part Context

This model belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The '18' prefix typically indicates the 1.8V supply variant. The 'QHTF21' denotes the specific package and performance class.
