Description

The SY58028U is a 2.5V/3.3V precision, high-speed, 4:1 differential CML multiplexer 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 inputs. The differential input includes Micrel's unique, 3-pin 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 50 source terminated CML, with extremely fast rise/fall times guaranteed to be less than 60ps.

The SY58028U operates from a 2.5V ±5% supply or a 3.3V ±10% supply and is guaranteed over the full industrial temperature range of 40°C to +85°C. For applications that require LVPECL outputs, consider the SY58029U or SY58030U Multiplexers. The SY58028U is part of Micrel's high-speed, Precision Edge® product line.All support documentation can be found on Micrel's web site at www.micrel.com.
