San Jose, Calif.Pericom Semiconductor Corp. announced a next-generation high-speed switch for graphics interface between PCs and monitors based on Gen2 PCI Express (PCIeG2) and DisplayPort (DP) architectures.
The PI3PCIE2612-A and PI3PCIE 2612-B are aimed at accelerating the transition PC manufactures are now making to DP, a widely supported license-free digital a/v interconnect standard (www.vesa.org). Next generation PCs feature dual-function graphics ports capable of offering a DP output from its embedded graphics accelerator, or PCIeG2 output through enhanced graphics cards slots. PI3PCIE2612-A/B provides point-to-point connections between the PC chipsets to those of the DP connector or the x16 PCIeG2 slot for external graphics cards.
In a typical 1:2 DeMux configuration, the device offers 4 DP channels or 4 PCIeG2 lanes, providing the highest possible resolution. It also offers Aux channel for training sequence, and HPD for connectivity detection. Low R-on / C-on assures maximum signal transfer and low distortion. With bandwidth of 2.5GHz at -5dB, the device is well equipped to handle both DP signals at 2.7-Gbit/s and PCIeG2 signals at 5.0-Gbit/s.
Low crosstalk of -35dB at 2.5GHz minimizes transmission noise, and high isolation of -35dB at 2.5GHz helps minimize leakage current between the source and the drain. Low channel-to-channel skew of less than 35ns and bit-to-bit skew of less than 7ps, signals paths improves synchronization. High 8KV contact ESD protection on the DP path potentially eliminates external ESD protection devices.
The device is offered in 56-TQFN (5mm x 11mm, 0.5 pad pitch) package, operating at 3.3V power supply with two pin-out versions to comply with ATX and BTX style PC motherboards.
Pricing: 10Ku OEM pricing is $1.35.
Availability: Production quantities; offered in Pb-free and Green packaging.
Datasheets: PI3PCIE2612-A and PI3PCIE2612-B.
