S21805T-24.000-X-R

Oscillators Overview

The S21805T-24.000-X-R is a standard crystal oscillator (XO) manufactured by Aker Technology Corp, operating at a fixed output frequency of 24 MHz. It utilizes HCMOS logic levels for signal output and supports a supply voltage range from 1.8V to 3.3V. The device features an enable/disable control function and maintains a frequency stability of ±50 ppm with a load capacitance of 15 pF. Designed for surface-mount applications, it is housed in a compact 4-SMD, no-lead package measuring 5mm x 3.2mm x 0.95mm. The component operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Oscillators Feature Summary

• HCMOS output interface for digital clock signal generation
• Integrated enable and disable control functionality
• Surface-mount construction for automated assembly

Oscillators Applications

• Digital system clock distribution
• Microprocessor timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix 'X-R' against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Ensure that the required enable/disable control logic aligns with the active-high or active-low specifications provided in the official documentation. Cross-reference the load capacitance requirements with the target circuit design to maintain the specified ±50 ppm stability.

Oscillators Selection Notes

Select this component when a 24 MHz HCMOS clock source is required with low-voltage operation capabilities down to 1.8V. Consider the 4-SMD no-lead footprint for space-constrained PCB layouts. Evaluate the ±50 ppm stability requirement against the system's timing tolerance needs. Confirm that the operating temperature range of -40°C to +85°C meets the environmental conditions of the intended application.

Oscillators Part Context

This part belongs to the S21805T series of surface-mount crystal oscillators from Aker Technology Corp. The series offers various frequency options and packaging styles designed for general-purpose digital electronics. The S21805T variant specifically denotes a standard XO configuration with HCMOS outputs, distinguishing it from other series members that may feature LVCMOS or differential outputs.

Oscillators Replacement Considerations

Direct substitutes include other 24 MHz HCMOS oscillators in compatible 4-SMD packages with similar voltage ranges. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
