Micrel, Inc. ULTRA-PRECISION DIFFERENTIAL LVPECL 2:1 MUX with INTERNAL TERMINATION Precision Edge® Precision ESd Y5g8e0®18U SY58018U Features Guaranteed AC performance over temperature and voltage: - DC to 5Gbps data throughput - DC to > 4GHz f MAX (clock) - < 260ps propagation delay - < 110ps tr / tf times Ultra-low crosstalk-induced jitter: 0.7ps RMS Ultra-low jitter design: - < 1ps RMS random jitter - < 10ps PP deterministic jitter - < 10ps PP total jitter (clock) Unique input termination and VT pin accepts DCand AC-coupled inputs (CML, PECL, LVDS) 800m V (100k) LVPECL output swing Power supply 2.5V ±5% or 3.3V ±10% - 40°C to +85°C temperature range Available in 16-pin (3mm x 3mm) QFN package APPLICATIONS Redundant clock distribution SONET/SDH clock/data distribution Loopback Fibre Channel distribution Precision Edge® DESCRIPTION The SY58018U is a 2.5V/3.3V precision, high-speed, 2:1 differential MUX capable of handling clocks up to 4GHz and data up to 5Gbps. 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 100m V without any level shifting or termination resistor networks in the signal path. The outputs are 800m V, 100k patible, LVPECL, with extremely fast rise/fall times guaranteed to be less than 110ps. The SY58018U 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 SY58017U or for 400m V LVPECL outputs the SY58019U. The SY58018U is part of Micrel’s high-speed, Precision Edge® product line.
