18QHTF21-63.050-PD

Overview

The 18QHTF21-63.050-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 63.05 MHz with an LVCMOS output logic level. The device is powered by a 1.8V supply voltage and features a Standby (Power Down) control function. It utilizes a 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports Standby (Power Down) mode for power management
• Utilizes LVCMOS output logic interface
• Compact 4-SMD No Lead surface mount package

Applications

• General electronic circuits requiring precise clock signals
• Embedded systems utilizing low-voltage logic interfaces
• Portable devices requiring compact oscillator solutions

Procurement Notes

Verify the specific frequency suffix matches the required 63.05 MHz application. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD No Lead package footprint fits the PCB layout constraints. Check for any specific operating temperature range requirements not detailed in general descriptions.

Selection Notes

Select this component when a 63.05 MHz clock signal is required with LVCMOS compatibility. The 1.8V supply requirement must be compatible with the host system's power rails. The small 2.0x1.6 mm package is suitable for space-constrained designs. Verify that the Standby feature meets power efficiency needs.

Part Context

This part belongs to the 18QHTF21 series of SMD oscillators from Mercury Electronics. The series typically offers various frequencies within a compact form factor. The 'PD' suffix indicates the inclusion of a Power Down pin or functionality. This series is designed for applications requiring reliable timing in small footprints.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical electrical specifications but different frequency suffixes, such as 18QHTF21-63.000-PD if frequency tolerance allows. Cross-referencing with other manufacturers' 2.0x1.6mm 1.8V LVCMOS XO packages is necessary for equivalent performance.
