ICS889831
LOW SKEW, 1-TO-4
DIFFERENTIAL LVPECL-TO-LVPECL/ECL FANOUT BUFFER
GENERAL DESCRIPTION
ICS
The ICS889831 is a high speed 1-to-4 Differential-
to-LVPECL/ECL Fanout Buffer and is a member
HiPerClockS™ of the HiPerClockS™family of high performance
clock solutions from ICS. The ICS889831 is
optimized for high speed and very low output
skew, making it suitable for use in demanding applications
such as SONET, 1 Gigabit and 10 Gigabit Ethernet, and Fibre
Channel. The internally terminated differential input and
VREF_AC pin allow other differential signal families such as
LVDS, LVHSTL and CML to be easily interfaced to the input
with minimal use of external components.The device also has
an output enable pin which may be useful for system test
and debug purposes. The ICS889831 is packaged in a small
3mm x 3mm 16-pin VFQFN package which makes it ideal
for use in space-constrained applications.

Pullup
Positive supply pins.
Synchronizing clock enable. When LOW, Q outputs will go LOW and nQ
outputs will go HIGH on the next LOW transition at IN inputs. Input
threshold is VCC/2V. Includes a 37kΩ pull-up resistor. Default state is
HIGH when left floating. The internal latch is clocked on the falling edge
of the input signal IN. LVTTL / LVCMOS interface levels.
Inverting differential clock input. 50Ω internal input termination to VT.
Reference voltage for AC-coupled applications.
Termination input.
Non-inverting differential clock input. 50Ω internal input termination to VT.
Negative supply pin.
Differential output pair. LVPECL / ECL interface levels.
NOTE: Pullup refers to internal input resistors. See Table 2, Pin Characteristics, for typical values.
