Chipset Server Backplane Server PCIe Gen 1, 2 (Trace, eg. FR4) PCIe Gen 1, 2 (Trace) PCIe Gen 1, 2 (Trace, eg. FR4) Repeater The IDT 89HP0504PB is a 5Gbps PCIe(R) Repeater device featuring IDT EyeMaxTM 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 89HP0504PB, 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. Block Diagram The 89HP0504PB contains four high speed channels as shown in the following diagram. Each channel can be routed to different outputs. Depending on user configuration via mode selections, input traffic can be muxed, demuxed, or looped back. Powerdown (PDB) and Receiver Detection Reset (RSTB) are provided for state and channel control.
