100311 Low Skew 1:9 Differential Clock Driver
100311
Low Skew 1:9 Differential Clock Driver
General Description
The 100311 contains nine low skew differential drivers,
designed for genera tion of multiple, mini mum skew differential clocks from a single differential input (CLKIN,
CLKIN
). If a single-ende d input is desir ed, the VBB output
pin may be used to driv e the rema ining inpu t line. A HIGH
on the enable pin (EN
) will force a LOW on all of the CLK
n
outputs and a HIGH on all of the CLKn output pins. The
100311 is ideal for distributing a signal throughout a system
without worrying about the original signal becoming too
corrupted by undesirable delays and skew.
Features
■ Low output-to-output skew
■ 2000V ESD protection
■ 1:9 low skew clock driver
■ Differential inputs and outputs
■ Available to industrial grade temperature range
(PLCC package only)

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
Note 1: The “Absolute Maximum Ratings” are those values beyon d which
the safety of the dev ice cannot be guaranteed. T he device sh ould not be
operated at these limit s. The parametric values defin ed in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recomme nded O peratin g Cond itions ” table will defin e the condition s
for actual device operation.
Note 2: ESD testing conf orm s t o M I L-STD-883, Method 3015.

Note 3: The specified limits represent the “worst case” value for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guardbanding can be achieved by decreasing the all owable syste m opera ti ng r ange s. Co ndi ti ons fo r t est ing shown in the ta ble s are chosen to guarantee operation under “worst case” conditions.
