ICS651M

Clock Buffers, Drivers Overview

The ICS651M is a low skew, single-input to four-output LVCMOS clock buffer from the Renesas 621S series. It features sub-50fs RMS additive phase jitter and supports input frequencies up to 200 MHz. The device operates on a supply voltage range of 1.71 V to 3.465 V, typically covering 1.8 V to 3.3 V applications. It exhibits a maximum propagation delay of 4.5 ns and functions within an industrial temperature range of -40°C to +105°C. Packaged in an 8-pin CMG format with a 0.5 mm pitch, it is designed for high-speed timing distribution.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'M' against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory details may vary by production batch. Ensure the ordering part number matches the required lead count and moisture sensitivity level (MSL 1) for your assembly process.

Clock Buffers, Drivers Selection Notes

Select this component when sub-50fs jitter performance is critical for signal integrity. Verify that the system power supply remains stable within the 1.71 V to 3.465 V range to ensure correct logic levels. Consider the 4.5 ns propagation delay for timing budget calculations in high-frequency designs requiring precise clock alignment across multiple loads.

Clock Buffers, Drivers Part Context

The ICS651M belongs to the Renesas 621S family of clock buffers. This series is engineered for cost-effective, high-speed timing solutions using LVCMOS outputs. It serves as a direct replacement for legacy ICSClock products, maintaining compatibility with standard digital interfaces while offering improved jitter characteristics for modern high-bandwidth applications.

Clock Buffers, Drivers Replacement Considerations

Consult official substitution guides for equivalent parts within the 621S family. Verify pinout compatibility and electrical parameters before replacing existing designs with alternative manufacturers' components.
