I547-2P3-19.200 MHZ

Oscillators Overview

The I547-2P3-19.200 MHZ is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by ILSI. It operates at a nominal frequency of 19.2 MHz with a clipped sine wave output. The device requires a 3.3V supply voltage and draws a maximum current of 1.5 mA. It utilizes a crystal base resonator and is housed in a surface-mount ceramic package measuring 3.20mm x 2.50mm. The component is designed for operation within an industrial temperature range of -40°C to 85°C.

Oscillators Feature Summary

• Temperature-compensated stability using a crystal base resonator
• Clipped sine wave output signal generation
• Low power consumption suitable for portable applications

Oscillators Applications

• Telecommunications equipment requiring stable clock signals
• Portable electronic devices with limited power budgets
• Industrial control systems operating in variable temperatures

Oscillators Procurement Notes

Verify the specific datasheet version for the I547-2P3-19.200 MHZ to confirm RoHS compliance status and exact pinout configuration. Ensure that the 3.3V supply requirement aligns with the target system's voltage rails. Cross-reference the 1.5mA maximum current draw against total system power constraints. Confirm the 3.20mm x 2.50mm footprint matches the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a stable 19.2 MHz reference is required in space-constrained designs. The TCXO technology provides better frequency stability than standard oscillators without the complexity of oven-controlled units. Consider the 3.3V supply constraint and clipped sine output compatibility with downstream logic circuits. The small ceramic package facilitates high-density board assembly.

Oscillators Part Context

This part belongs to the ILSI I547 series of surface-mount TCXOs. The series offers various frequency options including 12.8 MHz, 19.2 MHz, and 32.0 MHz variants. These components share common packaging dimensions and electrical characteristics, differing primarily in their nominal operating frequencies. The series targets applications needing reliable timing sources in compact form factors.

Oscillators Replacement Considerations

Direct substitutes include other ILSI I547 series parts such as I547-2P3-12.800 MHZ or I547-2P3-32.000 MHZ if frequency adjustment is permissible. Verify that any replacement maintains the 3.3V supply and 1.5mA current limits.
