Overview
The 18QHTF21-72.834-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 72.834 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications with a supply voltage of 1.8V. It features a Standby (Power Down) function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.
Feature Summary
- Supports Low Voltage CMOS (LVCMOS) output logic for digital interfacing
- Includes Standby (Power Down) mode capability for energy efficiency
- Utilizes a surface-mount 4-SMD No Lead package for compact integration
Applications
- Clock signal generation for embedded systems
- Timing reference for communication interfaces
- Power management circuits requiring standby modes
Procurement Notes
Verify the specific operating temperature range and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the 4-SMD No Lead package footprint matches the PCB layout specifications to avoid assembly issues.
Selection Notes
Select this component when a precise 72.834 MHz timing source is required in space-constrained designs. The 1.8V operation makes it suitable for modern low-power portable electronics. Consider the LVCMOS interface compatibility with the host processor or FPGA. The integrated power-down feature adds value for battery-operated applications requiring extended standby times.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a manufacturer specializing in quartz crystals and oscillators. The series typically offers standard XO configurations in small form factors. Mercury Electronics has a long history in the frequency control industry, providing reliable components for various electronic applications.
Replacement Considerations
Check for direct substitutes within the 18QHTF21 series offering different frequencies but identical pinouts and electrical characteristics. Verify compatibility with other manufacturers' 2.0x1.6mm LVCMOS oscillators if supply constraints exist.
