| Micrel, ULTRA PRECISION 8:1 MUX WITH INTERNAL TERMINATION AND 1:2 CML FANOUT BUFFER Precision Precision SY58037U s Selects between 1 of 8 inputs, and provides two precision, low skew CML output copies s Guaranteed AC performance over temperature and voltage: • DC to 5Gbps throughput • <450ps propagation delay IN-to-Q VIN 300mV • <70ps tr / tf time • <15ps skew output-to-output s Unique, patent-pending, channel-to-channel isolation design provides superior crosstalk performance s Ultra-low jitter design • <1psRMS random jitter • <10psPP deterministic jitter • <10psPP total jitter clock • <0.7psRMS crosstalk-induced jitter s Unique, patent-pending, input termination and VT pin accepts DC- and AC-coupled inputs CML, PECL, LVDS s 400mV CML output swing s source terminated outputs minimize round-trip reflections s Power supply 2.5V ±5% or 3.3V ±10% s to +85°C temperature range s Available in 44-pin 7mm x 7mm MLF package Precision The SY58037U 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 SY58037U distributes clock frequencies from DC to 4GHz and data rates to 5Gpbs guaranteed over temperature and voltage. The SY58037U 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 source-terminated CML with extremely fast rise/fall time guaranteed to be less than 70ps. The SY58037U features a patent-pending isolation design that significantly improves channel-to-channel crosstalk performance. The SY58037U operates from a 2.5V ±5% or 3.3V ±10% supply and is guaranteed over the full industrial temperature range of to +85°C. The SY58037U is part of Micrel’s high-speed, Precision product line.
