83940DYI-01LF

Overview

The Renesas Electronics 83940DYI-01LF is a low skew, 1-to-18 LVPECL-to-LVCMOS/LVTTL fanout buffer. It features two selectable clock inputs: the PCLK/nPCLK pair accepts LVPECL, CML, or SSTL levels, while the LVCMOS_CLK input accepts LVCMOS or LVTTL levels. The device provides eighteen low impedance LVCMOS/LVTTL outputs designed to drive 50Ω series or parallel terminated transmission lines. It supports full 3.3V, full 2.5V, and mixed voltage operating modes.

Feature Summary

Eighteen LVCMOS/LVTTL outputs with 16Ω typical output impedance
Selectable LVCMOS_CLK or LVPECL clock inputs
Characterized for 3.3V, 2.5V, and mixed voltage operation

Applications

Clock distribution systems requiring defined performance
Applications demanding well-defined repeatability
LVPECL to LVCMOS/LVTTL signal conversion

Procurement Notes

This component is discontinued. Verify availability through authorized distributors for remaining stock. Check for end-of-life notices and last-time-buy deadlines. Ensure compatibility with existing designs before procurement.

Selection Notes

Select this part for applications requiring high-output count fanout from differential LVPECL sources. Verify supply voltage requirements match the specific 3.3V, 2.5V, or mixed mode configuration needed for the target system logic levels.

Part Context

Part of the ICS83940 family. Manufactured by Renesas Electronics (formerly IDT). Designed for high-performance clock distribution in digital systems.

Replacement Considerations

Verify pinout and electrical specifications against potential substitutes. Consider newer generation buffers with similar output counts and input/output voltage compatibility.
