8535AGI-01LFT

Overview

The Renesas 8535AGI-01LFT is a low skew, high-performance clock buffer and multiplexer designed for signal distribution. It features a 2:4 input-to-output ratio, accepting LVCMOS or LVTTL single-ended inputs and translating them to four differential 3.3V LVPECL outputs. The device supports a maximum operating frequency of 266 MHz with a typical output skew of 30 ps and part-to-part skew of 200 ps maximum. It operates on a single 3.135V to 3.465V supply within an ambient temperature range of -40°C to 85°C. Packaged in a 20-TSSOP (0.173", 4.40mm wide) surface-mount format, it includes internally synchronized output enable to prevent runt pulses.

Feature Summary

• Converts single-ended LVCMOS/LVTTL inputs to four differential 3.3V LVPECL outputs
• Maximum operating frequency of 266 MHz with typical output skew of 30 ps
• Internally synchronized output enable eliminates runt pulses during asynchronous assertion/deassertion
• Available in lead-free (RoHS 6) 20-TSSOP package

Applications

• Clock distribution networks requiring LVCMOS to LVPECL translation
• High-speed digital systems demanding low skew performance
• Data communication equipment utilizing LVPECL logic levels

Procurement Notes

Verify the suffix 'LF' confirms lead-free (RoHS 6) compliance and 'T' indicates tape-and-reel packaging. Confirm the specific revision matches the required RoHS standard version. Check current availability status as component lifecycle stages may change. Ensure the 20-TSSOP footprint aligns with the target PCB design constraints.

Selection Notes

Select this component when a 2:4 fanout buffer is needed to drive LVPECL loads from LVCMOS sources. Verify that the 266 MHz maximum frequency meets system timing requirements. Ensure the 3.3V supply voltage range is compatible with the system power rails. Consider the 20-TSSOP package size for board space limitations compared to other packages in the 8535A family.

Part Context

This part belongs to the Renesas 8535A series of low skew clock buffers. It serves as a replacement for older variants like the ICS8535I-11. The 'AGI' designation typically refers to the automotive-grade or specific industrial qualification within the broader 8535A family, offering guaranteed skew characteristics for repeatability.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Review the 8535A family datasheet for pin-compatible alternatives such as the 8535AGI-31LF, noting differences in input/output configurations.
