18QHTF21-45.7143-PD

Oscillators Overview

The 18QHTF21-45.7143-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 45.7143 MHz with an LVCMOS output signal. The device functions on a 1.8V supply voltage and includes a standby (power down) feature for energy management. It utilizes a 4-SMD, no lead surface mount package with dimensions of 2.00mm x 1.60mm.

Oscillators Feature Summary

• Supports low-power operation via standby mode
• Provides LVCMOS output signal compatibility
• Utilizes compact surface mount packaging

Oscillators Applications

• General timing applications requiring 45.7143 MHz reference
• Low-power electronic systems
• Devices utilizing LVCMOS logic interfaces

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant matches the design requirements. Confirm that the 1.8V supply voltage aligns with the target system power rails. Ensure the 4-SMD no lead footprint corresponds to the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 45.7143 MHz clock source is required for LVCMOS-compatible circuits. The choice depends on the necessity for a 1.8V operating voltage and the availability of a 2.0x1.6mm surface mount footprint. Consider the standby functionality if power conservation during idle states is a critical design parameter.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within a compact form factor. The -PD suffix typically indicates the inclusion of a power-down or standby control function, distinguishing it from continuous-operation variants in the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 45.7143 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical electrical parameters and physical dimensions to ensure seamless integration.
