18QHTF21-13.235-PD

Overview

The 18QHTF21-13.235-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.235 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy 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 applications requiring low power consumption and precise timing.

Feature Summary

• Supports LVCMOS output logic for standard digital interface compatibility
• Includes standby mode to reduce power consumption during idle periods
• Utilizes a compact surface-mount package for space-constrained designs

Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontrollers and processors
• Consumer electronics requiring low-power oscillators

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against your system requirements before procurement. Ensure the 1.8V supply voltage aligns with your power architecture. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Check for any specific RoHS or environmental compliance certifications required for your region. Always refer to the official datasheet for final electrical specifications.

Selection Notes

Select this component when a 13.235 MHz clock signal is required with low power constraints. The 1.8V supply voltage makes it suitable for modern low-voltage digital circuits. The standby feature is advantageous for battery-operated devices. Consider the small 2.0x1.6mm footprint if board space is limited. Ensure the load capacitance requirements match your circuit design.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same form factor. The 'PD' suffix indicates the inclusion of a power-down function. Similar parts in the series include different frequencies such as 51.2 MHz or 6.0 MHz, maintaining consistent package and voltage characteristics.

Replacement Considerations

Direct replacements must match the 13.235 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that substitute components support the standby function if critical. Cross-reference with other manufacturers offering similar SMD oscillators in the 2.0x1.6mm package size.
