18QHTF21-114.270-PD

Overview

The 18QHTF21-114.270-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a standard frequency of 114.270 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports Low Voltage Complementary Metal-Oxide-Semiconductor (LVCMOS) output interface
• Includes standby mode capability for power down functionality
• Utilizes surface-mount technology with no lead design

Applications

• General clock signal generation in electronic circuits
• Data communication systems requiring precise timing
• Embedded systems utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure that the 1.8V supply voltage aligns with your power rail specifications. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to ensure reliability under your environmental conditions.

Selection Notes

Select this component when a 114.270 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage for low-power applications. The small 2.0x1.6 mm package size makes it suitable for space-constrained designs. Evaluate the need for standby functionality if power efficiency during idle states is a priority for the target application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various standard frequencies and supports LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down or standby pin feature, allowing for active power management within the circuit design.

Replacement Considerations

Direct substitutes must match the 114.270 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical parameters such as phase noise and stability before substitution.
