DESCRIPTION
■ Selects between 1 of 8 inputs, and provides two
precision, low skew CML output copies
■ 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)
■ 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, input termination and VT
pin accepts DC- and AC-coupled inputs (CML, PECL,
LVDS)
■ 400mV CML output swing
■ 50source 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 ×

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 50Ω
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 –40°C to +85°C. The SY58037U is part of Micrel’s
high-speed, Precision Edge® product line.
