General Description
The 89HT0816P is a Signal Retimer/Conditioners used to improve signal integrity for enhanc-
ing system performance and reliability across long PCB traces or cables. It removes both
random and deterministic jitter from the input signal eliminating inter-symbol interference,
and resets the output jitter budget. It provides sixteen differential, 8Gbps PCIe Express
®
3.0
channels, supporting up to 8 full lanes. It also fully support PCIe Express 5Gbps and 2.5Gbps
features. The T0816P is targeted to meet the high-performance needs of PCIe
®
Gen 3/2/1
applications.
Applications
IDT’s Retimer products fit into server, storage, and blade products, as well as Consumer Elec-
tronics and Communications applications.
