8535AGI-21LFT

Overview

The Renesas Electronics Corporation 8535AGI-21LFT is a low skew, high performance 1-to-4 Crystal Oscillator/LVCMOS-to-3.3V LVPECL fanout buffer. It features selectable single-ended clock or crystal inputs that accept LVCMOS or LVTTL levels and translate them to 3.3V LVPECL outputs. The device supports a maximum output frequency of 266MHz with typical output skew of 30ps and maximum part-to-part skew of 200ps. It operates on a full 3.3V supply within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Four differential 3.3V LVPECL outputs
• Selectable LVCMOS/LVTTL CLK or crystal inputs
• Maximum output frequency: 266MHz
• Output skew: 30ps (typical)

Applications

• Crystal Oscillator/LVCMOS-to-3.3V LVPECL Fanout Buffer

Procurement Notes

Verify the specific suffix 'LFT' against official documentation to confirm reel packaging versus tube configuration, as standard listings may indicate tube packaging for this series. Confirm current lifecycle status, as related models in the 8535I-21 family have been discontinued. Ensure RoHS compliance details match the required environmental standards for the target assembly process.

Selection Notes

Select this component when a 1-to-4 fanout buffer with LVPECL outputs is required from LVCMOS or crystal inputs. Verify that the 266MHz maximum frequency and 3.3V supply voltage align with system requirements. Consider the 20-TSSOP package dimensions and operating temperature range of -40°C to 85°C for compatibility with the design constraints.

Part Context

The 8535AGI-21LFT belongs to the 8535I-21 series of clock buffers. It serves as a replacement for older ICS8535I-11 models. The device is manufactured by Renesas Electronics Corporation and falls under the category of Clock Generators and Support Products, specifically designed for applications demanding well-defined performance and repeatability.
