IDT retimers were developed with the goal to improve signal integrity while at the same time doubling the transmission range. They minimize random & deterministic jitter of input signals and are thus perfectly suited for blade servers, enterprise storage or communication systems which require longer cable lines or backplane traces.
The most recent additions to the extensive product range are the 89HT0808P and 89HT0816P retimers. They are the first of their kind to fully support the new PCIe automatic link equalization process, simplifying system design and improving reliability of PCIe compliant adapter cards or host bus adapters.
The 8 channel 89HT0808P retimer and the 16 channel 89HT0816P retimer are able to provide data communication rates of 8 Gbps per channel across twice the range as standard PCIe 3.0 devices and via typical system backplanes, at the same time improving system performance and reliability and reducing material costs, since the overall design complexity is reduced.
Both retimers comprise a very powerful analogue frontend and are linked to a continuous time linear equalizer (CTLE), a five-level decision feedback equalizer (DFE) and a clock & data recovery unit.
The very sensitive input offers dynamic optimization options and is able to restore low quality signals and to eliminate randomized and deterministic jitter, exceeding the thresholds of the PCIe 3.0 specification. In order to enable rapid in-system testing, an extensive suite of diagnostic loopback characteristics was integrated in IDT's retimer monitoring functions. An evaluation board is available for IDT's 89HT0808P and 89HT0816P retimers, together with a software utility with a graphic user interface.
IDT's extensive signal integrity product range comprises solutions for industry standard interfaces such as PCIe Gen 2 and Gen 3, USB 3, XAUI, SATA, SAS and Serial RapidIO® and is available in a variety of channel numbers and casing sizes.
