18QHTF21-35.430-PD

Oscillators Overview

The 18QHTF21-35.430-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 35.43 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low voltage CMOS (LVCMOS) output logic levels
• Includes standby capability for power down management
• Utilizes surface mount no lead package design

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no lead package footprint matches the PCB layout design to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 35.43 MHz clock source is required for digital systems operating at 1.8V. The LVCMOS interface ensures compatibility with standard logic families. Consider the small form factor for space-constrained designs. Verify environmental temperature ranges if the application involves extreme conditions beyond standard commercial limits.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent packaging and electrical characteristics. The PD suffix indicates the inclusion of a power down feature. Mercury Electronics has established itself as a manufacturer of frequency control products since 1973.

Oscillators Replacement Considerations

Compatible substitutes include other 18QHTF21 series variants with different frequencies such as 18QHTF21-51.200-PD or 18QHTF21-30.300-PD, provided the frequency difference is acceptable for the application. Direct replacements must maintain the same 1.8V supply, LVCMOS output, and 4-SMD package.
