18QHTF21-101.000-PD

Overview

The 18QHTF21-101.000-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 101 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down function via a standby control input. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy management
• Delivers LVCMOS output signals

Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system synchronization

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper assembly and electrical connectivity.

Selection Notes

Select this component when a precise 101 MHz clock source is required for low-power applications. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the small form factor for space-constrained designs. Verify that the standby feature meets your power management strategy needs.

Part Context

This part belongs to the Mercury Electronics SMD oscillator series, which includes various frequencies and packages. The 'PD' suffix indicates the inclusion of a power-down control pin. Similar parts in the lineup offer different frequencies such as 51.2 MHz or 67 MHz while maintaining the same package and voltage characteristics.

Replacement Considerations

Direct substitutes must match the 101 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Check for equivalent power-down functionality. Cross-reference with other manufacturers offering similar SMD oscillators if availability is an issue.
