| Micrel, Inc. ULTRA PRECISION 8:1 MUX WITH INTERNAL TERMINATION AND 1:2 400mV LVPECL FANOUT BUFFER Precision Precision SY58039U s Selects between 1 of 8 inputs, and provides 2 precision, low skew LVPECL output copies s Guaranteed AC performance over temperature and voltage: • DC to 5Gbps throughput • <490ps propagation delay IN-to-Q VIN 100mV • <85ps 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 LVPECL output swing 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 SY58039U 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 SY58039U distributes clock frequencies from DC to 4GHz, and data rates to 5Gpbs guaranteed over temperature and voltage. The SY58039U 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 400mV, 100Kcompatible LVPECL with extremely fast rise/fall times guaranteed to be less than 85ps. The SY58039U features a patent-pending isolation design that significantly improve channel-to-channel crosstalk performance. The SY58039U 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 SY58039U is part of Micrel’s high-speed, Precision product line.
