651MILF-PAC

Overview

The Renesas Electronics 651MILF is a low skew clock buffer belonging to the 651 series. It features one input and four outputs, supporting LVCMOS logic levels for both signal interfaces. The device operates within a supply voltage range of 1.425 V to 2.625 V and handles maximum frequencies of 200 MHz on both input and output channels. Maximum propagation delay is specified at 5 ns. Packaged in an SOIC-8 surface-mount format, it functions across an industrial temperature range from -40°C to +85°C with a typical operating current of 50 mA.

Feature Summary

• Four-output LVCMOS clock buffering with low skew characteristics
• Supports maximum input and output frequencies up to 200 MHz
• Operates on a low voltage supply range of 1.425 V to 2.625 V
• Available in compact SOIC-8 surface-mount packaging

Applications

• Low voltage digital system clock distribution
• High-speed data acquisition timing synchronization
• Industrial control board clock generation

Procurement Notes

The 651MILF component is listed as obsolete or discontinued by major distributors such as Mouser. Verification of availability requires checking specific authorized channels for remaining stock or end-of-life status. Procurement planning should account for potential supply constraints due to its discontinued lifecycle stage.

Selection Notes

Select this component when a low-voltage (1.425V–2.625V) 1:4 clock buffer is required. Ensure the design supports LVCMOS signaling and operates within the 200 MHz frequency limit. Verify that the SOIC-8 package fits the PCB layout constraints and that the -40°C to +85°C temperature range meets environmental requirements.

Part Context

This part belongs to the Renesas 651 series of clock buffers. It is distinct from other series like the 551 or 524, which operate at different voltage levels (e.g., 3V–5.5V for the 551 series). The 651 series is specifically designed for lower voltage applications compared to standard 3.3V or 5V buffered clocks.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative components must be selected based on functional equivalence (LVCMOS, 1:4 ratio, <2.625V supply) rather than direct cross-reference lists.
