Overview
The 18QHTF21-84.11438-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 84.11438 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down control feature. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm by 1.6mm.
Feature Summary
- Integrates LVCMOS output logic for digital interface compatibility
- Supports standby mode via power-down control signal
- Utilizes a surface-mount 4-SMD no-lead package design
Applications
- Digital clock generation in communication modules
- Timing reference for high-speed data buses
- Embedded system clock sources requiring low voltage operation
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational specifications. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues during manufacturing.
Selection Notes
Select this component when a precise 84.11438 MHz timing source is required within space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. Consider the LVCMOS output swing levels to ensure compatibility with downstream logic inputs without additional buffering.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in Taiwan's crystal industry. This series typically offers standard XO configurations with various frequency options and supply voltages.
Replacement Considerations
Direct substitutes must match the 84.11438 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if available in competitor datasheets.
