Device Overview
The IDT 89HP0504PB (P0504PB) is a 5Gbps PCIe® Repeater
device featuring IDT EyeBoost™ technology that compensates for cable
and board trace attenuations and ISI jitter, thereby extending connection
reach. The device is optimized for PCIe Gen1 and Gen2 high speed
serial data streams and contains four data channels, each able to
process 5Gbps transmission rates. Each channel consists of an input
equalizer and amplifier, signal detection with glitch filter, as well as
programmable output swing and de-emphasis. Allowing for application
specific optimization, the P0504PB, with its configurable receiver and
transmitter features, is ideal for PCIe applications using a wide
combination of cables and board trace materials.
All modes of active data transfer are designed with minimized power
consumption. In full shutdown mode, the part consumes less than
40mW in worst case environmental conditions.
