DESCRIPTION
Precision Edge®
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.

100KEP circuits are designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. The
circuit is in a test socket or mounted on a printed circuit board and traverse airflow greater than 500lfpm is maintained.
Single-ended input operation is limited VEE ≤ –3.0V in LVECL mode.
VIHCMR (min) varies 1:1 with VEE. The VIHCMR range is referenced to the most positive side of the differential input signal.
