PI3PCIE2612-A
High Bandwidth, 6-Differential Channel
1:2 DP/PCIe Gen2 Display Mux, ATX Pinout
Features
• 6 Differential Channel, 1 to 2 demux that will support
5.0Gbps PCIexpress Gen2 signals on one path, and DP 1.1
signals on the second path
• Insertion Loss for high speed channels @ 5.0 Gbps: -5.0dB
• Low Bit-to-Bit Skew , 7ps max (between '+' and '-' bits)
• Latched Mux Select
• Matched paths for all PCIe signals
• Low Crosstalk for high speed channels: -35dB@2.5 GHz
• Low Off Isolation for high speed channels: -35dB@2.5 GHz
• VDD Operating Range: 3.3V ± 10%
• ESD Tolerance: 8kV HBM on Display Port Path output
3kV HBM on PCI-Express path output
• Low channel-to-channel skew, 35ps max
• Packaging (Pb-free & Green):
– 56 TQFN (ZFE)
Description
Pericom Semiconductor’s PI3PCIE2612-A one to two Mux/
Demux is targeted for next generation systems that combine PCI-
Express gen-II signals with Display Port Signals.
Application
Routing DP and PCIExpress Gen1 or Gen2 signals with low signal
attenuation.
