2.5V/3.3V 1:10 DIFFERENTIAL
Precision Edge™
SY100EP111U
LVPECL/LVECL/HSTL CLOCK DRIVER
FEATURES
■ 2.5V and 3.3V power supply options
■ Guaranteed AC parameters over temperature:
• f = 3GHz
Precision Edge™
MAX
• < 25ps output-to-output skew
• < 250ps t / t
DESCRIPTION
r
f
• < 400ps propagation delay
■ Wide temperature range: –40°C to +85°C
■ Differential design
The SY100EP111U is a high-speed, low skew 1-to-10
differential fanout buffer designed for clock distribution in
new, high-performance systems. The internal 2:1 mux
allows the input to select between two differential clock
sources.
The device is specifically designed for low skew. The
interconnect scheme and metal layout are carefully
optimized for minimal gate-to-gate skew within the device.
Wafer characterization and process control ensure
consistent distribution of propagation delay from lot to lot.
The VBB output is intended for use as a reference
voltage for single-ended reception of ECL signals to that
device only. When using VBB for this purpose, it is
recommended that VBB is decoupled to VCC via a 0.01µF
capacitor.
■ V output for single-ended input applications
BB
■ Fully compatible with industry standard 100K I/O
levels
■ Available in 32-pin TQFP package
