89HP0504PBZBNRG

Specialized Overview

The Renesas Electronics 89HP0504PBZBNRG is a four-channel PCIe Gen1 and Gen2 signal repeater designed for high-speed serial data streams up to 5Gbps. It utilizes IDT EyeBoost technology to compensate for cable and board trace attenuation, as well as ISI jitter, allowing for extended connection reach. The device features programmable receiver equalization (up to 24dB), transmitter swing (0.5V to 0.95V peak-to-peak), and de-emphasis (-6.5dB). It supports various transfer modes including direct connect, cross-connect, multicast, channel muxing, and demuxing. The component operates within a commercial temperature range of 0°C to 70°C or an industrial range of -40°C to 85°C, housed in a 36-pin VFQFPN package.
