Combination re-driver meets current and standby power requirements
The PI3EQX12904A PCIe 3.0/SATA3 combo re-driver from Diodes has linear equalisation that supports speeds up to 8Gbits per second to provide laptop, notebook, industrial PC and embedded system developers with a robust, multi-protocol linear re-driver that offers a flexible interface while also meeting current and standby power requirements, says the company.
Demand for interface devices that can drive extended PCB track lengths without degrading the signal is growing as solid state drives (SSDs) are used in place of hard disk drives (HDDs) in notebooks, laptops, industrial PCs and embedded systems. The P13EQX12904A complies with both PCIe and SATA protocols, to be a single product that can be used in multiple products, Diodes adds.
Designers need to address the potential performance issues inherent with driving control and data signals across a switch fabric, cables, PCB tracks or other connections. In addition to providing the extra drive required to achieve this, the PI3EQX12904A adds programmable equalisation, linear swing and flat gain capability.
The PI3EQX12904A supports PCIe 3.0 and SATA3 protocols over serial links running at 8Gbits per second (PCIe 3.0) and 6Gbits per second (SATA3). It features four 100Ohm differential CML data I/O signals and is transparent to link training. Its adaptive power management features include automatic low power mode with automatic receiver detection. In slumber mode, the inputs are monitored for any activity, and if detected, the corresponding channel automatically switches to active mode.
The PI3EQX12904A is available in a 42-TQFN (ZH) package.
