PI3PCIE3212
3.3V, PCI Express® 3.0, 1-Lane, 2-Channel,
8Gbps, 2:1 Mux/DeMux Switch w/ Single Enable
Description
Pericom Semiconductor’s PI3PCIE3212 is a PCIe Gen3.0, 8Gbps,
4 to 2 differential, bi-directional channel multiplexer/demulti-
plexer switch. Due to its low bit-to-bit skew, high channel-to-
channel noise isolation and bandwidth, this product is ideal for
PCI Express® 3.0 signal switching at 8.0Gbps.
Application
Switch a PCI Express 3.0 lane output between two PCI Express
lane inputs. Applications include NBs, PCs, servers, and other
embedded devices. Routing of PCI Express 3.0, DP1.2, USB3.0,
SAS2.0, SATA3.0, XAUI, RXAUI signals with low signal attenu-
ation.
