M9999-020707 hbwhelp@micrel.com or (408) 955-1690 DESCRIPTION ■ Selects between 1 of 8 inputs, and provides 2 precision, low skew LVPECL output copies ■ Guaranteed AC performance over temperature and voltage: • DC to 4.5Gbps throughput • <500ps propagation delay IN-to-Q (VIN ≥ 100mV) • <100ps tr /tf time • <15ps skew (output-to-output) ■ Unique, patent-pending, channel-to-channel isolation design provides superior crosstalk performance ■ Ultra-low jitter design: • <1psRMS random jitter • <10psPP deterministic jitter • <10psPP total jitter (clock) • <1psRMS cycle-to-cycle jitter • <0.7psRMS crosstalk-induced jitter ■ Unique, patent-pending, input termination and VT pin accepts DC- and AC-coupled inputs (CML, PECL, LVDS) ■ 800mV LVPECL output swing ■ Power supply 2.5V ±5% or 3.3V ±10% ■ –40°C to +85°C temperature range ■ Available in 44-pin (7mm × × × × × 7mm) MLF® package FEATURES ULTRA PRECISION 8:1 MUX WITH INTERNAL TERMINATION AND 1:2 LVPECL FANOUT BUFFER Precision Edge® SY58038U APPLICATIONS ■ Data communication systems ■ All SONET/SDH data/clock applications ■ All Fibre Channel applications ■ All Gigabit Ethernet applications Rev.: C Amendment: /0 Issue Date: February 2007 The SY58038U 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 SY58038U distributes clock frequencies from DC to 3.5GHz, and data rates to 4.5Gpbs guaranteed over temperature and voltage. The SY58038U 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 800mV, 100K compatible LVPECL with extremely fast rise/fall times guaranteed to be less than 100ps. The SY58038U features a patent-pending isolation design that significantly improves channel-to-channel crosstalk performance. The SY58038U 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 SY58038U 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.
