I547-2P3-20.000 MHZ

Oscillators Overview

The I547-2P3-20.000 MHZ is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by ILSI America LLC. It operates at a nominal frequency of 20 MHz and utilizes a 3.2 mm x 2.5 mm ceramic surface-mount package. The device supports a supply voltage of 3.3 V and delivers a clipped sine wave output with a minimum amplitude of 0.8 V p-p. It features high frequency stability of ±2 ppm and an aging rate of ±1 ppm per year, making it suitable for precision timing applications.

Oscillators Feature Summary

• Low jitter performance without PLL-based architecture
• Compatible with lead-free processing standards
• Provides stable clipped sine wave output signal

Oscillators Applications

• Fibre Channel Server & Storage systems
• Sonet/SDH network infrastructure
• 802.11 / Wifi communication modules
• T1/E1 and T3/E3 system clocking

Oscillators Procurement Notes

Verify the specific part number suffix to confirm the operating temperature range and control voltage specifications. Ensure compatibility with the target circuit's power supply requirements and load conditions. Confirm that the clipped sine wave output level meets the input sensitivity of the receiving component before finalizing procurement.

Oscillators Selection Notes

Select this component when precise frequency stability within ±2 ppm is required in a compact surface-mount form factor. Consider the 3.3 V supply constraint and the need for a clipped sine wave output interface. Evaluate the ±1 ppm/year aging characteristic against long-term system accuracy requirements compared to standard VCXO or XO alternatives.
