M9999-020707 hbwhelp@micrel.com or (408) 955-1690 Rev.: D Amendment: /0 Issue Date: February 2007 DESCRIPTION ■ Provides crosspoint switching between any input pair to any output pair ■ Guaranteed AC performance over temperature and voltage: • DC to >5Gbps throughput • <350ps propagation delay • <60ps tr /tf times • <25ps 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) • <0.7psRMS crosstalk-induced jitter ■ Unique, patent-pending, 50Ω input termination extended CMVR, and VT pin accepts DC- and AC- coupled differential inputs ■ 400mV CML output swing ■ 50Ω source terminated outputs minimize round-trip reflections ■ Power supply 2.5V ±5% or 3.3V ±10% ■ –40°C to +85°C temperature range ■ Available in 44-pin (7mm × × × × × 7mm) MLF® package ■ Pb-Free green package FEATURES ULTRA PRECISION 4× × × × ×4 CML SWITCH WITH INTERNAL I/O TERMINATION Precision Edge® SY58040U APPLICATIONS ■ Data communication systems ■ All SONET/SDH data/clock applications ■ All Fibre Channel applications ■ All Gigabit Ethernet applications The SY58040U is a low jitter, low skew, high-speed 4×4 crosspoint switch optimized for precision telecom and enterprise server/storage distribution applications. The SY58040U distributes clock frequencies from DC to 4GHz, and data rates to 5Gbps guaranteed over temperature and voltage. The SY58040U 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 (200mVpp) without any level shifting or termination resistor networks in the signal path. The outputs are 50Ω source-terminated CML with extremely fast rise/fall times guaranteed to be less than 60ps. The SY58040U features a patent-pending isolation design that significantly improves on channel-to-channel crosstalk performance. The SY58040U 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 SY58040U 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.
