1. general description the cbtl06gp212 is a six-channel (?hex?) mu ltiplexer for displayp ort and pci express applications at generation 2 (?gen2?) spe eds. it provides four differential channels capable of 1 : 2 switching or 2 : 1 multiplexing (bidirectional and ac-coupled) pci express or displayport signals, using high-bandwidth pass-gate technology. it provides support for high common-mode/bias voltage on the high speed differential channels. additionally, it provides for switching/multiple xing of the hot plug detect signal as well as the aux or ddc (direct display control) signals, for a total of six channels on the display side. the aux and ddc channels provide a f our-position multiplexer such that an additional level of multiplexing can be accomplished when aux and ddc i/os are on separate pins of the display source device. the cbtl06gp212 is designed for gen2 sp eeds, at 5.0 gbit/s for pci express or 5.4 gbit/s for displayport. it consumes 2 ma current (typical) in operational mode and provides a shutdown function to support battery-powered applications. a typical application of cbtl06gp212 is on motherboards where one of two gpu display sources needs to be selected to connect to a display sink device or connector. a controller chip selects which path to use by setting a select signal high or low. due to the non-directional nature of the signal paths (which use high-bandwidth pass gate technology), the cbtl06gp212 can also be used in the reverse topology, e.g., to connect one display source device to one of two display sink devices or connectors. 2. features cbtl06gp212 high performance displayp ort switch with high common-mode voltage support rev. 1 ? 2 may 2012 product brief ? 1 : 2 switching or 2 : 1 multiplexing of displayport (v1.2 - 5.4 gbit/s) or pci express (v2.0 - 5.0 gbit/s) signals ? 4 high-speed differential channels with 2 : 1 muxing/switching for displayport or pci express signals ? 1 channel with 4 : 1 muxing/switching for aux at 1 mbit/s or ddc signals ? 1 channel with 2 : 1 muxing/switching for single-ended hpd signal ? r on on dp high-speed channels: 6 ? low insertion loss: ? ? 0.5 db at 100 mhz ? ? 1.5 db at 1.35 ghz ? ? 2.5 db at 2.7 ghz ? low crosstalk: ? 35 db at 2.7 ghz ? low off-state isolation: ? 30 db at 2.7 ghz ? low return loss: ? 8db at 2.7ghz ? very low intra-pair skew (5 ps typical) ? very low inter-pair skew (< 80 ps) ? high-bandwidth analog pass-gate technology ? 3 db bandwidth at 5 ghz ? supports a wide range of common-mode/bias voltage on high speed differential channels ? switch/multiplexer positi on select cmos input ? shutdown mode cmos input ? supports backdrive protection ? single 3.3 v power supply ? supports high-speed signal switching over a wide common-mode range and differential swing
