Application Information

The TMUXHS221LV is an analog high-speed mux/demux that can be used for routing differential as well as single ended CMOS signals through it. The device can be used for many high speed and low speed interfaces up to 3Gbps including the following:

  • Universal Serial Bus (USB) 2.0 HS, FS, and LS
  • Embedded Universal Serial Bus (eUSB) 2.0 HS, FS, and LS
  • Inter-Integrated Circuit (I2C) Bus
  • System Management Bus (SMBus™)
  • Universal Asynchronous Receiver-Transmitter (UART™)
  • Debug interface signals
  • Mipi® Camera Serial Interface (CSI-2), Display Serial Interface (DSI)
  • PCIe® clock
  • DisplayPort™ Auxiliary and Hot Plug Detect Signals
  • Universal Serial Bus Type C Sideband Use (USB-C™ SBU) signals
  • Low Voltage Differential Signaling (LVDS)

An available GPIO pin of a controller or hard tie to voltage level H or L can easily control the mux or demux selection pin (SEL) of the device as an application requires.

Many interfaces require AC coupling the capacitors between the transmitter and receiver. The 0201 or 0402 capacitors are the preferred option, but other capacitors may be used depending on interface speed and signal integrity needs. If AC coupling capacitors are used on both sides of the TMUXHS221LV, then ensure the device is biased from either side, as there is no internal biasing to the device.
