181MI-02LF

Overview

The Renesas Electronics Corporation 181MI-02LF is a low EMI clock generator featuring spread spectrum technology. It operates within an input frequency range of 28 MHz to 48 MHz and accepts clock or crystal inputs. The device supports core voltages of 3.3V and 5V, with a supply voltage range of 3.135V to 5.5V. Typical peak-to-peak cycle-to-cycle jitter is 250 ps, while maximum peak-to-peak jitter is 300 ps. It is housed in an 8-SOIC package with a length of 4.9 mm and functions across an operating temperature range of -40°C to 85°C.

Procurement Notes

Verify the specific suffix requirements for lead-free compliance and package variations when sourcing replacements. Confirm that the target application environment remains within the specified -40°C to 85°C operational limits. Ensure power supply stability falls between 3.135V and 5.5V to maintain signal integrity. Check current availability status as lifecycle stages may affect long-term supply continuity.

Selection Notes

Select this component when minimizing electromagnetic interference is critical for system compliance. The integrated spread spectrum feature eliminates the need for external filtering in many designs. Verify that the required input frequency falls within the 28 MHz to 48 MHz range. Ensure the design accommodates the 8-SOIC package dimensions and thermal characteristics.
