Overview
The 18QHTF21-8.6016-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 8.6016 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down function for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Includes power-down functionality to reduce current consumption during standby
- Utilizes a small form factor surface-mount package
Applications
- General clock signal generation in embedded systems
- Timing reference for microcontrollers and processors
- Data communication interfaces requiring precise clock sources
Procurement Notes
Verify the specific suffix 'PD' confirms the power-down feature against the manufacturer's official datasheet. Ensure the operating temperature range meets system requirements. Confirm that the 1.8V supply voltage aligns with the target circuit design before procurement.
Selection Notes
Select this component when a low-voltage 1.8V clock source is required with minimal footprint. The power-down capability makes it suitable for battery-operated devices where standby power conservation is critical. Ensure the 8.6016 MHz frequency matches the system timing specifications.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'PD' suffix indicates power-down support, while 'OE' variants typically offer enable/disable control. This specific model provides a balance of size and functionality for portable electronics.
Replacement Considerations
Direct replacements must match the 8.6016 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent power-down functionality. Cross-reference with other Mercury models or compatible industry-standard oscillators ensuring identical pinout and electrical characteristics.
