I537-2O7-40.000 MHZ

Oscillators Overview

The I537-2O7-40.000 MHZ is a temperature-compensated crystal oscillator (TCXO) manufactured by ILSI America, designed for surface-mount applications. It operates at a nominal frequency of 40 MHz and utilizes a 4-SMD, no-lead ceramic package measuring 2.5 mm x 3.2 mm. The device provides a clipped sine wave output with a minimum amplitude of 0.8 V p-p. It functions within a supply voltage range of 2.7 V to 3.3 V, drawing a maximum current of 2 mA. The unit supports an operating temperature range from -40°C to +85°C and features a frequency stability of ±1.5 ppm over the specified temperature range.

Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required operating temperature range (-40°C to +85°C) and frequency tolerance specifications. Confirm the output waveform requirement for clipped sine wave compatibility with downstream circuitry. Ensure the procurement documentation references the correct RoHS compliance status and lead-free termination finish details provided in the manufacturer datasheet.

Oscillators Selection Notes

Select this component when a compact TCXO with low phase noise is required for high-speed digital interfaces. The 40 MHz frequency suits standard clocking requirements for serial communication protocols. Consider the 2 mA current consumption for power-sensitive designs. The ceramic package offers robust mechanical stability compared to plastic alternatives in harsh environments.

Oscillators Part Context

This part belongs to the ILSI I537 series of surface-mount TCXOs. The series is characterized by small form factors and low power consumption. It is engineered to replace larger through-hole oscillators or less stable crystal units in modern telecommunications and computing hardware where space and signal integrity are critical constraints.

Oscillators Replacement Considerations

Direct replacements must match the 40 MHz frequency, 4-SMD footprint, and clipped sine wave output. Verify that substitute parts support the -40°C to +85°C industrial temperature range and ±1.5 ppm stability. Check pinout compatibility and supply voltage requirements before integration.
