differential CML 1:8 fanout buffer. The SY58031U is
optimized to provide eight identical output copies with less
than 20ps of skew and less than 10ps
process clock signals as fast as 6GHz.
termination architecture that allows the SY58031U to directly
interface to CML, LVPECL, and LVDS differential signals
(AC- or DC-coupled) without any level-shifting or termination
resistor networks in the signal path. The result is a clean,
stub-free, low-jitter interface solution. The CML outputs
feature 400mV typical swing into 50ý loads and provide an
extremely fast rise/fall time guaranteed to be less than 60ps.
3.3V ±10% supply and is guaranteed over the full industrial
temperature range (–40°C to +85°C). For applications that
require high-speed 1:8 LVPECL fanout buffers, consider
the SY58032U and SY58033U. The SY58031U is part of
Micrel’s high-speed, Precision Edge
