8535AGI-01LF

Overview

The Renesas Electronics Corporation 8535AGI-01LF is a clock buffer and multiplexer IC designed for high-performance timing applications. It features a 2:4 input-to-output ratio, accepting LVCMOS or LVTTL single-ended inputs and generating four differential LVPECL outputs. The device supports maximum output frequencies up to 266 MHz and operates within a supply voltage range of 3.135 V to 3.465 V. Packaged in a 20-TSSOP format with dimensions of 0.173 inches (4.40 mm) width, it functions reliably across an ambient temperature range of -40°C to +85°C.

Feature Summary

• 2:4 Input/Output Ratio: Converts two single-ended inputs to four differential LVPECL outputs.
• High Frequency Performance: Supports maximum output frequencies of 266 MHz.
• Input Compatibility: Accepts LVCMOS and LVTTL input signal levels.
• Low Skew Design: Optimized for applications requiring precise timing and repeatability.

Applications

• Clock distribution networks requiring low skew performance.
• Systems utilizing crystal oscillators or single-ended clock sources.
• Digital circuits demanding translation from LVCMOS/LVTTL to LVPECL levels.

Procurement Notes

Verify component authenticity through authorized distributors due to the presence of legacy part number aliases such as ICS8535I-01. Confirm RoHS compliance status via current datasheets, as manufacturing sites and material compositions may have changed over time. Ensure the specific suffix matches the required package and environmental specifications for the target application.

Selection Notes

Select this component when a 2:4 fanout buffer with LVPECL outputs is required. Ensure the system power supply can maintain the 3.135 V to 3.465 V range. Verify that the input source provides compatible LVCMOS or LVTTL levels. Consider the 20-TSSOP package constraints for PCB layout and thermal management within the -40°C to +85°C operating window.

Part Context

This device belongs to the FemtoClock family of clock solutions from Renesas Electronics. It serves as a successor or alternative to earlier Integrated Device Technology (IDT) products like the ICS8535I-01. The component is categorized under Clock Buffers & Drivers within the broader Clock & Timer ICs subcategory.
