Logic - Signal Switches, Multiplexers, Decoders

SY89208VMI-TR is a logic-signal switch specifically designed for high speed bidirectional parallel-bus applications. It uses one input port and two output ports to function as an active low-impedance, electronic bus splitter. Furthermore, SY89208VMI-TR is ideal for use in applications involving passing of signals at frequency range up to 2.0 GHz and cascading up to five devices.

Application Field

The SY89208VMI-TR can be used in a variety of applications, including firewire and USB 2.0 repeaters, high speed graphics video routing, clock networks and data transfer applications in computer systems, switching or multiplexing of communications and storage bus signals, and cardbus and PCI express expansion slots.

Working Principle

SY89208VMI-TR is a dual-channel, active passive-state switch. It contains two independent channels, each with a single input port and two output ports aimed at descending a signal to two separate outputs. Both of the output ports are enabled for either input port polarity, deriving its appropriate output direction from the logic control.When VCC is greater than the logic high threshold voltage and GND is lower than the logic low threshold voltage, the logic state of the control port determines the output direction of the signals from the input port. When the control is LOW, signals from the input port will flow from OUT0 to OUT1 and vice versa when the control is HIGH. This offers a wide variety of applications and flexibility in the system design.When no input is applied to any of the ports, the output remains in its passive state; this allows the device to be used in analog and digital bus-splitting applications.

SY89208VMI-TR is designed to pass signals to two separate output ports at a frequency range up to 2.0 GHz, making it ideal for high-speed applications such as firewire and USB 2.0 repeaters, high-speed graphics video routing, and clock networks.Additionally, the SY89208VMI-TR can be cascaded up to five devices, allowing for multiple connections and more complex system designs. It is extremely versatile and can be used in a variety of applications.
