CBTL02042-43 CMOS Multiplexer-Demultiplexer Switches

NXP's switches support high-bandwidth systems while minimizing power consumption

Image of NXP Semiconductor's CBTL02042/43 CMOS Multiplexer/Demultiplexer SwitchesNXP Semiconductors'CBTL02042A/B and CBTL02043A/B are two differential channel, 2-to-1 multiplexer/demultiplexer switches for PCI Express Gen2 (CBTL02042A/B) and Gen3 (CBTL02043A/B) or other high-speed serial interface applications. These devices can switch two differential signals to one of two locations. Using a unique design technique, NXP has minimized the impedance of the switch in such a way that the attenuation observed through the switch is negligible, and also minimized the channel-to-channel skew as well as channel-to-channel crosstalk, as required by the high-speed serial interface. These devices also allow expansion of existing high speed ports for extremely low power. These mux/demux switches are suitable for routing high-speed signals in applications with PCIe Gen2 (CBTL02042A/B), PCIe Gen 3 (CBTL02043A/B), DisplayPort 1.2, USB 3.0, and SATA 6 Gbit/s.

  • Two bidirectional differential channel, 2:1 mux/demux
  • High-speed signal switching for PCIe Gen2: 5 Gbit/s (CBTL02042A/B) and Gen3: 8 Gbit/s (CBTL02043A/B)
  • Available in a very thin DHVQFN20 package
  • Low return loss
  • Shutdown pin (XSD) for power-saving mode
  • Low crosstalk
  • Low off-state isolation
  • High bandwidth
