Signal Switches, Multiplexers, Decoders FAQ

How does the device handle AC-coupled inputs?

An internal high impedance resistor divider biases the VT pin to allow input AC-coupling. For these applications, the VT pin should be bypassed with a 0.1µF low ESR capacitor to VCC.

What is the maximum data rate supported?

The SY56040AR can process data patterns up to 6.4Gbps.
