SY58039U

The SY58039U is a low jitter, low skew, high-speed 8:1 multiplexer with a 1:2 differential fanout buffer optimized for precision telecom and enterprise server distribution applications. The SY58039U distributes clock frequencies from DC to 4GHz, and data rates to 5Gpbs guaranteed over temperature and voltage.

The SY58039U differential input includes Micrel's unique, 3-pin input termination architecture that directly interfaces 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 outputs are 400mV, 100Kcompatible LVPECL with extremely fast rise/fall times guaranteed to be less than 85ps.

The SY58039U features a patent-pending isolation design that significantly improve channel-to-channel crosstalk performance.

The SY58039U operates from a 2.5V ±5% or 3.3V ±10% supply and is guaranteed over the full industrial temperature range of 40°C to +85°C. The SY58039U is part of Micrel's high-speed, Precision Edge® product line.Data sheets and support documentation can be found on Micrel's web site at www.micrel.com.
