ULTRA PRECISION 4×4 CML

SWITCH WITH INTERNAL

I/O TERMINATION

4×4 crosspoint switch optimized for precision telecom and

enterprise server/storage distribution applications. The

SY58040U distributes clock frequencies from DC to 4GHz,

and data rates to 5Gbps guaranteed over temperature and

voltage.

3-pin input termination architecture that directly interfaces

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

100mV (200mV

resistor networks in the signal path. The outputs are 50Ω

source-terminated CML with extremely fast rise/fall times

guaranteed to be less than 60ps.
