Overview
The 18QHTF21-64.080-PD is a 64.08 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates with an LVCMOS output logic and requires a 1.8V supply voltage. The device features a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for standard clock signal generation applications requiring precise frequency stability.
Feature Summary
- Supports Low Voltage CMOS (LVCMOS) output interface
- Includes Standby (Power Down) functionality
- Utilizes a compact 4-SMD No Lead package
Applications
- General clock signal generation
- Digital circuit timing reference
- Embedded system clock sources
Procurement Notes
Verify the specific ordering suffix 'PD' to ensure the correct package type and lead configuration are obtained. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Check the datasheet for exact operating temperature ranges and load capacitance requirements before finalizing the design integration.
Selection Notes
Select this component when a low-profile 2.0x1.6mm footprint is required for space-constrained designs. Ensure the system supports LVCMOS logic levels and provides a stable 1.8V power supply. Consider the standby feature if power efficiency during idle states is a critical design parameter for the application.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized small outline package. The 'PD' suffix typically denotes specific packaging or handling characteristics defined by the manufacturer for this product line.
Replacement Considerations
Direct substitutes must match the 64.08 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package dimensions. Verify pin compatibility and electrical specifications against original datasheets before substitution.
