SY58029U - Micrel Semiconductor

SY58029U ULTRA PRECISION DIFFERENTIAL LVPECL 4:1 MUX

The SY58029U is a 2.5V/3.3V precision, high-speed, 4:1 differential multiplexer with 100k LVPECL (800mV) compatible outputs, capable of handling clocks up to 4GHz and data streams up to 5Gbps. In addition, a 1:2 fanout buffer provides two copies of the selected inputs. The differential input includes Micrel’s unique, 3-pin input termination architecture that.
