Description

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 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 800mV LVPECL, (100k temperature compensated) with extremely fast rise/ fall times guaranteed to be less than 110ps.The SY58029U 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 CML outputs, consider the SY58028U. For 400mV LVPECL outputs, consider the SY58030U. The SY58029U is part of Micrel's high-speed, Precision Edge®product line.
