General Description
The VSC6464 is a 64x64 asynchronous (flow-through) or synchronous (clocked) high-speed crosspoint
switch. Any input can be multiplexed to any, some, or all outputs. The switch is fully non-blocking. All I/Os are
single-ended ECL. The part is packaged in a 208-pin plastic quad flat pack and consumes less than 8 Watts from
a single -2V power supply.
In the asynchronous mode, high speed digital data up to 500Mb/s can be switched with less than 25% pulse
width distortion. Skew is less than 1.5 ns between any two paths through the switch. In broadcast operation (one
input routed to two or more outputs), any two outputs will exhibit less than 750ps of skew.
In the synchronous mode, high-speed digital data up to 250 Mb/s can be switched with less than 750ps out-
put-to-output skew. The input and output registers have separate clock inputs.
