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.
