674R-01LFT

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas 674R-01LFT is a clock divider integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 5.5V and supports a maximum frequency of 235MHz. The device features a 2:2 input-to-output ratio and contains one circuit. It is housed in a 28-SSOP package with a width of 0.154 inches (3.90mm). The component is designed for surface mount installation and functions without differential inputs or outputs. It lacks an internal PLL and does not support frequency multiplication, serving specifically as a divider.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The 674R-01LFT is listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking distributor stock status directly. Alternative components from the same family or newer generations should be evaluated for new designs due to discontinuation status.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component only if a 2:2 division ratio and frequencies up to 235MHz are required. Ensure the system design accommodates the 28-SSOP footprint. Verify that single-ended I/O interfaces meet the system requirements, as differential options are not available in this specific part number.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the 674R series of clock dividers. It is distinct from Renesas clock generators which typically include PLLs and multiple output drivers. The 674R series focuses on simple frequency division tasks without the complexity of frequency synthesis or jitter attenuation provided by other Renesas timing families.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Renesas technical support for recommended replacements or evaluate similar clock dividers from other manufacturers that match the 235MHz speed grade and 28-SSOP package constraints.
