8535AG-21LF

Overview

The Renesas 8535AGI-21LF is a clock generator and support product featuring four LVPECL outputs. It belongs to the 8535I-21 series and is manufactured by Renesas Electronics. The component is currently listed as obsolete or end-of-life, with limited availability noted in distributor records. It functions as a buffer within the clock and timer ICs category, designed for high-performance timing applications requiring differential signaling.

Feature Summary

• Four differential 3.3V LVPECL outputs
• Maximum output frequency of 266MHz
• Input levels: LVCMOS or LVTTL
• Operating temperature range: -40°C to 85°C

Applications

• High-speed digital systems requiring low skew clock distribution
• Telecommunications infrastructure equipment
• Data communication networks

Procurement Notes

This component is officially discontinued by Renesas Electronics. Distributors list it as having restricted supply or being out of stock. Verification of authenticity and condition is critical when sourcing from secondary markets due to its end-of-life status.

Selection Notes

Designers should consider this part only for maintenance of existing hardware. New designs require alternative active components from the Renesas portfolio that offer similar LVPECL buffering capabilities with current manufacturing support.

Part Context

The 8535AGI-21LF is part of the ICS8535 family, which provides low-skew clock buffers. The 'GI' suffix typically indicates a specific package variant, often TSSOP, while 'LF' denotes lead-free compliance. It serves as a fanout buffer for translating single-ended inputs to differential LVPECL outputs.
