18QHTF21-93.600-PD

Overview

The 18QHTF21-93.600-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 93.6 MHz and utilizes LVCMOS output logic. The device is designed for 1.8V supply voltage operation and includes a standby or power-down function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby and power-down functionality
• Compact surface-mount package design

Applications

• Precision frequency generation systems
• Digital signal processing circuits
• Communication equipment requiring stable clock signals

Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant matches the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure the 4-SMD no-lead footprint fits the PCB layout constraints.

Selection Notes

Select this component when a low-voltage 1.8V supply is required for the oscillator circuit. Consider the small 2.0x1.6 mm footprint for space-constrained designs. Verify that LVCMOS output levels are compatible with the receiving logic inputs. Evaluate the need for power-down control features to manage system power consumption during idle states.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard crystal oscillators. The series offers various frequencies and supply voltages. The 18QHTF21 model specifically denotes the 1.8V supply and 4-SMD package type. Mercury Electronics has been a pioneer in the crystal industry since 1973.

Replacement Considerations

The 25QHTF32-93.600-OE is a similar 93.6 MHz oscillator from Mercury United Electronics. However, it may differ in package size and voltage specifications. Verify electrical parameters before substitution.
