89HP0508PZBABG

Specialized Overview

The Renesas 89HP0508PZBABG is an 8-channel PCIe Gen2 signal repeater operating at 5Gbps. It utilizes IDT EyeBoost technology to compensate for cable and board trace attenuation and ISI jitter, extending connection reach. The device features programmable receiver equalization up to 30dB and de-emphasis up to -8.5dB. It supports channel mux, demux, multicast, and Z-switch modes via I2C configuration. Power consumption is minimized in active and shutdown states, with full shutdown drawing less than 80mW. It is housed in a 100-ball FPBGA package.
