18QHTF21-10.600-PD

Overview

The 18QHTF21-10.600-PD is a 10.6 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and features LVCMOS output logic. The device supports a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for applications requiring precise frequency control within low-power constraints.

Feature Summary

• Supports Standby (Power Down) mode for enhanced power efficiency
• Utilizes LVCMOS output logic for standard digital interface compatibility
• Compact 4-SMD, No Lead package design suitable for space-constrained layouts

Applications

• Battery-powered portable devices
• Low-power consumer electronics
• Embedded systems requiring precise clock signals

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Check the operating temperature range specifications to ensure reliability under your intended environmental conditions. Request the official datasheet from Mercury Electronics for final parameter validation.

Selection Notes

Select this component when a 10.6 MHz clock signal is required with minimal power consumption. The 1.8V operation makes it suitable for modern low-voltage digital circuits. Consider the small 2.0x1.6 mm footprint if board space is limited. The standby feature allows for dynamic power management in battery-operated equipment. Ensure the application does not require spread spectrum or other advanced modulation features not present in this standard XO model.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies while maintaining a consistent 1.8V supply and compact form factor. These oscillators are designed for general-purpose clocking applications where size and power efficiency are critical. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from standard continuous-operation variants within the same package family.

Replacement Considerations

Direct replacements must match the 10.6 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as current consumption and startup time. Cross-reference with other manufacturers offering similar low-profile oscillators only if they explicitly confirm equivalent performance metrics and mechanical dimensions.
