Overview
The 18QHTF21-65.0159-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 65.0159 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a Standby function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.
Feature Summary
- Supports Standby mode for power down functionality
- Utilizes LVCMOS output logic interface
- Compact 4-SMD No Lead surface mount package
Applications
- General clock signal generation
- Digital circuit timing reference
- Embedded system clock sources
Procurement Notes
Verify the specific frequency suffix matches the required 65.0159 MHz specification. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD No Lead package footprint is compatible with the PCB layout. Check for any specific operating temperature range requirements if the application involves extreme environmental conditions.
Selection Notes
Select this component when a precise 65.0159 MHz clock source is needed with low voltage operation. The LVCMOS output is suitable for standard digital logic interfaces. The small form factor makes it ideal for space-constrained designs. Consider the standby feature if power efficiency during idle periods is a priority for the overall system architecture.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a small SMD package. The 'PD' suffix likely indicates a specific packaging or tape-and-reel configuration. Mercury Electronics specializes in quartz crystals and frequency control products.
Replacement Considerations
Direct substitutes must match the 65.0159 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm 4-SMD package. Verify pinout compatibility before substitution. Other manufacturers offering similar XO specifications may serve as alternatives if electrical parameters are identical.
