SY58038U
Ultra-Precision, 8:1 MUX with Internal
Termination and 1:2 LVPECL Fanout Buffer
Precision EdgeВ® General Description
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 patented isolation design that
significantly improves channel-to-channel crosstalk
performance.
The SY58038U operates from a 2.5V В±5% or 3.3V В±10%
supply and is guaranteed over the full industrial
temperature range of –40В°C to +85В°C. The SY58038U is …
