S73305T-20.000-X-15-R

Oscillators Overview

The S73305T-20.000-X-15-R is a surface-mount clock oscillator from the Aker Technology S7 series, operating at a fixed output frequency of 20 MHz. It utilizes HCMOS output logic levels and maintains a frequency stability of ±50 ppm. The device supports a supply voltage range of 1.8 V to 3.3 V, with specific variants supporting enable/disable control at 3.3 V. It features a compact 4-pin SMD package measuring 7.0 mm in length, 5.0 mm in width, and 1.3 mm in height. The component operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Oscillators Feature Summary

• Provides stable 20 MHz clock signals via HCMOS output interface
• Supports low-profile surface mount packaging for space-constrained designs
• Features wide supply voltage compatibility ranging from 1.8V to 3.3V
• Includes enable/disable functionality for power management in 3.3V configurations

Oscillators Applications

• General digital system clock generation
• Embedded processor timing references
• Communication interface synchronization
• Consumer electronics timing circuits

Oscillators Procurement Notes

Verify the exact suffix configuration when ordering, as variations such as -CT or -R may indicate different tape-and-reel quantities or specific enable pin configurations. Confirm that the selected variant matches the required supply voltage and output enable requirements for the target application. Ensure compliance with RoHS directives if environmental regulations apply to the end product.

Oscillators Selection Notes

Select this component when a precise 20 MHz reference is required with HCMOS compatibility. Consider the S73305T series for its low profile and small footprint compared to larger through-hole alternatives. Evaluate the need for enable/disable control; if power saving is critical, ensure the specific 3.3V enable variant is chosen over standard versions. Check thermal performance against the -40°C to +85°C operational range.

Oscillators Part Context

This part belongs to the Aker Technology S7 series of surface-mount crystal oscillators. The series offers various frequencies and package sizes, with the S73305T specifically denoting the 7x5mm form factor. It serves as a direct replacement for older 4-pin SMD oscillators in modern compact electronic designs requiring reliable timing sources.

Oscillators Replacement Considerations

Direct substitutes include other 20MHz HCMOS oscillators in 4-SMD packages with similar dimensions (7x5mm) and ±50ppm stability. Verify pinout compatibility and supply voltage ranges before swapping. Cross-reference with manufacturers like Epson, NDK, or SiTime for equivalent SMD clock sources.
