The SY58011U is a 2.5V/3.3V precision, high-speed, fully
differential 1:2 CML fanout buffer. Optimized to provide two
identical output copies with less than 15ps of skew and less
than 10ps
(pk-pk)
total jitter, the SY58011U can process clock
signals as fast as 7GHz or data patterns up to 10.7Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that interfaces to LVPECL, LVDS,
or CML differential signals, (AC-coupled or DC-coupled) as
small as 100mV without any level-shifting or termination
resistor networks in the signal path. For AC-coupled input
interface applications, an on-board output reference voltage
(V
REF
-AC) is provided to bias the V
T
pin. The outputs are
compatible with 400mV typical swing into 50ý loads, with
extremely fast rise/fall times guaranteed to be less than
60ps.
The SY58011U operates from a 2.5V ±5% supply or
3.3V ±10% supply and is guaranteed over the full industrial
temperature range (–40°C to +85°C). For applications that
require LVPECL outputs, consider the SY58012U or
SY58013U 1:2 fanout buffer with 800mV and 400mV output
swing, respectively. The SY58011U is part of Micrel’s high-
speed, Precision Edge
®
product line. Datasheets and
