MK5818SLF

Overview

The MK5818SLF is a clock generator integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.97V to 3.63V and supports a maximum frequency of 16MHz. The device features one circuit with an input-to-output ratio of 2:2, utilizing LVCMOS outputs. It accepts clock or crystal inputs and incorporates a Phase-Locked Loop (PLL). Designed for surface mount installation, it is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm). The component is rated for operation between 0°C and 70°C.

Feature Summary

• Integrated PLL-based clock generation with 2:2 input-to-output ratio
• LVCMOS output interface supporting frequencies up to 16MHz
• Compatible with clock or crystal input sources
• Available in 8-SOIC surface-mount packaging

Applications

• General-purpose clock signal generation in embedded systems
• Timing reference distribution for digital logic circuits
• Consumer electronics requiring low-frequency clock sources

Procurement Notes

Verify the specific suffix 'SLF' against official Renesas documentation to confirm package type and temperature grade. Confirm current availability status as related variants may be obsolete. Ensure compatibility with 3.3V nominal supply rails given the 2.97V-3.63V operating range.

Selection Notes

Select this component when a fixed 2:2 multiplication ratio is required for 16MHz applications. Compare against the MK5811 series if higher frequencies or different ratios are needed. Verify that LVCMOS output levels meet the input requirements of downstream components.

Part Context

The MK5818 belongs to the MK58xx family of low EMI clock generators from IDT, now part of Renesas. These devices typically utilize proprietary spread spectrum technology to reduce electromagnetic interference. The MK5818 specifically targets lower frequency applications compared to other members of the series.

Replacement Considerations

Check for direct pin-compatible replacements such as the MK5818S or MK5818SF depending on package and temperature variations. Verify if the MK5811C or MK5812 offers suitable alternatives for similar timing requirements.
