Overview
The 18QHTF21-60.700-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 60.7 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a 1.8V supply voltage. It features a frequency stability of ±50 ppm and supports a standby or power-down function to conserve energy when not in use. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.
Feature Summary
- Supports standby mode for power management
- LVCMOS output interface compatibility
- Compact surface-mount packaging
Applications
- Battery-powered portable devices
- Low-power consumer electronics
- Communication modules requiring precise timing
Procurement Notes
Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply requirement aligns with the target system's power architecture. Ensure the 4-SMD no-lead package dimensions match the PCB footprint design. Check for any specific handling requirements related to electrostatic discharge during assembly.
Selection Notes
Select this component when a low-voltage, low-power oscillator is required for systems operating at 1.8V. The LVCMOS output ensures compatibility with standard digital logic families. Consider the ±50 ppm stability for applications where moderate frequency accuracy is sufficient. The standby feature makes it suitable for devices with intermittent usage patterns to extend battery life.
Part Context
Mercury Electronics Ind. Co., Ltd. has been manufacturing frequency control products since 1973 and is recognized as a pioneer in the crystal industry in Taiwan. The company produces a wide range of oscillators and resonators. This model belongs to their series of standard crystal oscillators designed for modern electronic applications requiring small form factors and low power consumption.
Replacement Considerations
Cross-reference with other 60.7 MHz LVCMOS oscillators from different manufacturers if supply constraints exist. Ensure replacement parts match the 1.8V supply voltage and 4-SMD package dimensions. Verify that alternative components offer comparable frequency stability and support standby functionality.
