Overview
Micrel, Inc.
ULTRA-PRECISION DIFFERENTIAL LVPECL 2:1 MUX with INTERNAL TERMINATION Precision Edge® Precision ESdY5g8e0®18U SY58018U FEATURES Guaranteed AC performance over temperature and voltage: • DC to 5Gbps data throughput • DC to > 4GHz fMAX (clock) • < 260ps propagation delay • < 110ps tr / tf times Ultra-low crosstalk-induced jitter: 0.
7psRMS Ultra-low jitter design: • < 1psRMS random jitter • < 10psPP deterministic jitter • < 10psPP total jitter (clock) Unique input termination and VT pin accepts DCand AC-coupled inputs (CML, PECL, LVDS) 800mV (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 100mV without any level shifting or termination resistor networks in the signal path.
The outputs are 800mV, 100k compatible, 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 400mV LVPECL outputs the SY58019U.
The SY58018U is part of Micrel’s high-speed, Precision Edge® product line.
