8535AGI-21LF

Overview

The Renesas 8535AGI-21LF is a clock generator and support product belonging to the 8535I-21 series. It functions as a 4 LVPECL output buffer. The component is currently listed with an end-of-life status by Mouser Electronics, indicating it is discontinued. The device utilizes a tube packaging format and carries the Renesas trademark. It falls under the sub-category of Clock & Timer ICs within the broader clock generators classification.

Feature Summary

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

Applications

• Clock distribution in high-performance computing systems
• Server and storage subsystem timing
• Telecommunications equipment synchronization

Procurement Notes

The 8535AGI-21LF is officially discontinued and no longer in active production. Availability is restricted to existing stock or surplus channels. Verification of RoHS compliance and specific lot dates is recommended when sourcing from third-party distributors due to the end-of-life status.

Selection Notes

This component serves as a low-skew fanout buffer for translating single-ended LVCMOS or LVTTL inputs to differential LVPECL outputs. Designers requiring similar functionality should consider the ICS8535I-11 replacement or newer Renesas clock buffer families, ensuring compatibility with 3.3V supply requirements and 266MHz maximum frequency specifications.

Part Context

Part of the 8535I-21 series from Renesas Electronics, designed for precise clock distribution. The 'GI' suffix typically denotes a specific package variant, while '21' indicates the pinout and output configuration. It is categorized under clock buffers and drivers, specifically for LVPECL applications.

Replacement Considerations

The datasheet notes that this part replaces the ICS8535I-11. Engineers should verify pin compatibility and electrical parameters against current Renesas offerings such as the 8535AGI-31LF if available, though the latter may have different input/output configurations.
