18QHTF21-13.501-PD

Overview

The 18QHTF21-13.501-PD is a 13.501 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates at a supply voltage of 1.8V. The component features a Standby (Power Down) function for power management. It is housed in a 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• LVCMOS output interface
• Standby (Power Down) capability
• Compact 4-SMD No Lead form factor

Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific frequency suffix matches the required 13.501 MHz application. Confirm the 1.8V supply requirement aligns with the target circuit design. Ensure the 4-SMD No Lead package footprint corresponds to the PCB layout specifications. Check for any specific operating temperature range requirements not explicitly detailed in general descriptions.

Selection Notes

Select this component when a low-voltage 1.8V operation is required. The compact 2.0x1.6 mm size is suitable for space-constrained designs. LVCMOS compatibility ensures direct interfacing with standard digital logic. The standby feature aids in power-sensitive applications requiring active control over oscillator states.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies within the same physical footprint. The 'PD' suffix indicates the inclusion of a power-down pin or functionality. These components are designed for high-reliability timing applications in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 13.501 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify that alternative manufacturers provide equivalent stability and phase noise specifications if critical. Ensure the replacement supports the standby function if utilized in the design.
