542MILFT

Overview

The Renesas 542MILFT is a clock fanout buffer and divider IC designed for high-speed signal distribution. It accepts a single clock input up to 156 MHz and provides divided outputs. The device operates within a supply voltage range of 3.3 V, with a maximum rating of 5.5 V. It features low skew performance and sub-50 fsec additive phase jitter characteristics. The component is housed in an 8-pin SOIC surface-mount package with a width of 0.154 inches (3.90 mm). It supports 3-state CMOS bus interfaces and is qualified for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Provides cost-effective generation of high-quality clock outputs divided from a primary clock input
• Delivers low skew performance with sub-50 fsec additive phase jitter for precise timing
• Reduces power consumption and board space requirements compared to alternative solutions

Applications

• High-speed clock distribution networks
• System synchronization circuits
• Digital signal processing systems requiring precise timing

Procurement Notes

Verify the specific suffix 'LFT' corresponds to lead-free compliance and tape-and-reel packaging configuration as defined by Renesas. Confirm that the operating frequency requirement does not exceed the 156 MHz limit at the intended supply voltage. Ensure thermal management aligns with the specified -40°C to +85°C industrial range. Cross-reference pin assignments against the official datasheet to prevent interface mismatches during integration.

Selection Notes

Select this component when a single input must be divided into multiple buffered outputs with minimal jitter. It is suitable for designs requiring 3-state control and CMOS compatibility. Consider the 8-pin SOIC footprint for space-constrained layouts. Evaluate if the 156 MHz maximum input frequency meets the system clock requirements before finalizing the design.

Part Context

The 542 series belongs to Renesas' clock buffer and driver portfolio, focusing on signal integrity and distribution. This specific model serves as a divider, reducing frequency while maintaining signal quality. It addresses the need for reliable clocking in digital systems where jitter and skew are critical performance parameters.
