differential multiplexer with 400mV LVPECL outputs, capable

of handling clocks up to 7GHz and data streams up to

10.7Gbps. In addition, a 1:2 fanout buffer provides two copies

of the selected input.

termination architecture that allows customers to interface to

any differential signal (AC- or DC-coupled) as small as 100mV

without any level shifting or termination resistor networks in

the signal path. The result is a clean, stub-free, low-jitter

interface solution. The outputs are 400mV LVPECL (100K

temperature compensated) with extremely fast rise/fall times

guaranteed to be less than 80ps.

3.3V ±10% supply and is guaranteed over the full industrial

temperature range of –40°C to +85°C. For applications that

require CML outputs, consider the SY58028U. For 800mV

LVPECL outputs, consider the SY58029U. The SY58030U is
