The CBTL06DP213EE,118 is a 6-channel bidirectional multiplexer from NXP designed for DisplayPort and PCIe signal switching. Its 11.1 GHz -3dB bandwidth keeps the eye open at 8.1 Gbps (DisplayPort 1.4) or 8 GT/s (PCIe 3.0) without needing a redriver for short board traces. Each channel can be configured as 2:1 or 4:1 mux/demux, giving you the topology flexibility to route four main-link lanes plus two AUX/DDC channels in a DP source, or to build a x4 PCIe lane switch.
Package and supply — what the 48-TFBGA footprint expects
Housed in a 48-TFBGA (5x5 mm ball array), this is a fine-pitch BGA that needs a controlled impedance breakout on the top layer. The single supply range of 3.0 V to 3.6 V aligns with standard 3.3 V DisplayPort and PCIe PHY rails — no extra regulator.
On-resistance and channel count — BOM fit check
Typical on-resistance is 14 Ohm, which is low enough for AC-coupled differential pairs at these data rates. The 6-channel count maps directly to a standard DisplayPort source: four main-link lanes plus two sideband channels (AUX+ and HPD). For PCIe, the same six channels cover a x4 link plus two spare lanes for sideband or as a spare.
