18QHTF21-31.608-OE

Oscillators Overview

The 18QHTF21-31.608-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 31.608 MHz with an LVCMOS output logic interface. The device requires a supply voltage of 1.8V and features enable/disable functionality for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0 x 1.6 mm. The unit supports an operating temperature range of -40°C to +85°C and maintains a frequency stability of ±50ppm.

Oscillators Feature Summary

• LVCMOS output logic interface
• Enable/disable control capability
• Compact 4-SMD no lead package

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Embedded systems utilizing LVCMOS interfaces
• Consumer electronics with space constraints

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no lead package footprint matches your PCB layout specifications. Check for any specific environmental certifications required for your application region.

Oscillators Selection Notes

Select this component when a precise 31.608 MHz clock signal is needed with low power operation. The LVCMOS output is suitable for direct interfacing with digital logic circuits. Consider the ±50ppm stability for applications not requiring ultra-high precision timing. The small form factor makes it ideal for dense PCB designs where space is limited.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within the same compact package. These oscillators are designed for general-purpose timing applications in consumer and industrial electronics. The 'OE' suffix typically denotes specific packaging or ordering options defined by the manufacturer.

Oscillators Replacement Considerations

Direct replacements must match the 31.608 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pin compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators if Mercury stock is unavailable.
