CA32C0404ILR

Oscillators Overview

The CA32C0404ILR is a crystal oscillator (XO) from the CA32 series by CTS-Frequency Controls. It operates at a nominal frequency of 4 MHz with an output waveform compatible with HCMOS and TTL logic levels. The device supports a supply voltage of 3.3V and features an enable/disable control function. It is housed in a compact 4-SMD, no-lead package measuring 3.20mm x 2.50mm. The unit is rated for operation between -40°C and 85°C and meets AEC-Q200 automotive standards.

Oscillators Feature Summary

• Supports enable/disable functionality for power management
• Delivers standard HCMOS/TTL output waveforms
• Complies with AEC-Q200 automotive qualification standards

Oscillators Applications

• Automotive electronic systems requiring certified clock sources
• Industrial control circuits needing stable timing references
• Embedded systems utilizing 3.3V logic interfaces

Oscillators Procurement Notes

Verify that the specific suffix 'ILR' corresponds to the 3.3V supply voltage variant, as other suffixes may indicate different voltage ratings such as 2.5V. Confirm the package dimensions match the 3.20mm x 2.50mm footprint required by the design. Ensure the operating temperature range of -40°C to 85°C aligns with the environmental conditions of the target application before finalizing procurement.

Oscillators Selection Notes

Select this component when a 4 MHz reference signal is required for 3.3V digital logic circuits. The choice is driven by the need for AEC-Q200 compliance in automotive contexts or general industrial reliability. Designers must ensure the board layout accommodates the 4-SMD no-lead package and that the enable pin is properly managed to utilize the low-power standby mode effectively.

Oscillators Part Context

This part belongs to the CA32 series of clock oscillators manufactured by CTS-Frequency Controls. The series provides various frequency options and voltage supplies within a small surface-mount form factor. These devices are designed to replace discrete crystal and resonator circuits, offering integrated stability and reduced board space for modern electronic designs.

Oscillators Replacement Considerations

Equivalent parts include CA32C0404INR and CA32C0404GNR, though these variants typically operate at 2.5V rather than 3.3V. Substitution requires careful verification of supply voltage compatibility and logic level thresholds to prevent circuit malfunction.
