83940DYLF

Overview

The Renesas 83940DYLF is a low skew, 1-to-18 LVPECL-to-LVCMOS/LVTTL fanout buffer. It features eighteen LVCMOS/LVTTL outputs with a typical output impedance of 16Ω. The device supports selectable clock inputs: the PCLK/nPCLK pair accepts LVPECL, CML, or SSTL levels, while the LVCMOS_CLK input accepts LVCMOS or LVTTL levels. It operates at full 3.3V, full 2.5V, and mixed voltage modes. Designed to drive 50Ω terminated transmission lines, it ensures well-defined performance and repeatability for clock distribution applications.

Feature Summary

Eighteen LVCMOS/LVTTL outputs with 16Ω typical output impedance
Selectable LVPECL/CML/SSTL or LVCMOS/LVTTL clock inputs
Low skew characteristics for precise clock distribution
Supports 3.3V, 2.5V, and mixed voltage operation

Applications

Clock distribution in high-speed digital systems
LVPECL to LVCMOS/LVTTL level translation
Driving 50Ω series or parallel terminated transmission lines
