Micrel, Inc. ULTRA-PRECISION DIFFERENTIAL 400mV LVPECL 2:1 MUX with INTERNAL TERMINATION Precision Edge® Precision ESdY5g8e0®19U SY58019U FEATURES ■ Guaranteed AC performance over temperature and voltage: DC to 10.7Gbps data throughput DC to > 7GHz fMAX (clock) < 240ps propagation delay < 70ps 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 DCcoupled and AC-coupled inputs (CML, PECL, LVDS) ■ 400mV (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 × 3mm) MLF® package APPLICATIONS ■ Redundant clock distribution ■ OC-3 to OC-192 SONET/SDH clock/data distribution ■ Loopback ■ Fibre Channel distribution Precision Edge® DESCRIPTION The SY58019U is a 2.5V/3.3V precision, high-speed, 2:1 differential MUX capable of handling clocks up to 7GHz and data up to 10.7Gbps. 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 400mV, 100k compatible, LVPECL, with extremely fast rise/fall times guaranteed to be less than 70ps. The SY58019U operates from a 2.5V ±5% supply or a 3.3V ±10% supply and is guaranteed...
