18QHTF21-35.320-PD

Oscillators Overview

The 18QHTF21-35.320-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 35.320 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features a standby mode to reduce power consumption during idle periods
• Utilizes a surface-mount 4-SMD no-lead package for automated assembly

Oscillators Applications

• Digital signal processing circuits requiring precise clock timing
• Communication systems utilizing standard frequency references
• Embedded microcontroller boards needing low-profile oscillators

Oscillators Procurement Notes

Verify the specific operating temperature range 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 2.0x1.6mm footprint matches your PCB layout constraints. Check for any specific handling instructions regarding ESD sensitivity associated with the SMD package type.

Oscillators Selection Notes

Select this component when a 35.320 MHz reference is required in a space-constrained environment. The LVCMOS output ensures direct interfacing with standard logic families without additional buffering. The inclusion of a power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Verify that the 1.8V operation matches the target system voltage.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor oscillators. The series typically offers various frequencies within a standardized 2.0x1.6mm package. This specific model provides a mid-range frequency option suitable for general-purpose digital applications rather than high-frequency RF uses.

Oscillators Replacement Considerations

Direct substitutes must match the 35.320 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering identical pinouts and electrical characteristics to ensure functional interchangeability without PCB redesign.
