IDT8535-01PGG8

Clock Buffers, Drivers Overview

The IDT8535-01PGG8 is a low skew, high-performance 1-to-4 LVCMOS-to-3.3V LVPECL fanout buffer manufactured by Renesas Electronics Corporation (formerly IDT). It translates single-ended LVCMOS or LVTTL clock inputs to four differential 3.3V LVPECL outputs. The device supports a maximum output frequency of 266MHz with a propagation delay of 1.9ns maximum. It features selectable CLK0 or CLK1 inputs for redundant applications and an internally synchronized clock enable pin to eliminate runt pulses. The component operates on a 3.3V supply and is available in a 20-pin TSSOP package.

Clock Buffers, Drivers Procurement Notes

Verify the manufacturer designation as Renesas Electronics Corporation, which acquired IDT. Confirm the specific suffix PGG8 corresponds to the commercial temperature grade (-40°C to +85°C) and TSSOP-20 package type as detailed in the ordering information section of the official datasheet.

Clock Buffers, Drivers Selection Notes

Select this component when converting standard logic level clocks to high-speed LVPECL signals with minimal skew. Ensure the input source matches LVCMOS or LVTTL voltage levels. Verify that the system can accommodate the required 3.3V power supply and negative VEE termination voltage for the LVPECL outputs.

Clock Buffers, Drivers Part Context

This part belongs to the IDT8535 family of low skew fanout buffers designed for high-performance clocking solutions. It serves as a bridge between standard logic inputs and high-speed differential output requirements, ensuring signal integrity across various industrial and commercial electronic designs.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include other variants of the IDT8535 series. Cross-referencing with ICS8535 models may be necessary, though electrical characteristics and pinouts should be verified against the official datasheet to ensure compatibility.
