MC100E310
5V ECL Low Voltage 2:8
Differential Fanout Buffer
Description
The MC100E310 is a low voltage, low skew 2:8 differential ECL
fanout buffer designed with clock distribution in mind. The device
features fully differential clock paths to minimize both device and
system skew. The E310 offers two selectable clock inputs to allow for
redundant or test clocks to be incorporated into the system clock trees.
The lowest TPD delay time results from terminating only one output
pair, and the greatest TPD delay time results from terminating all the
output pairs. This shift is about 10−20 pS in TPD. The skew between
any two output pairs within a device is typically about 25 nS. If other
output pairs are not terminated, the lowest TPD delay time results
from both output pairs and the skew is typically 25 nS. When all
outputs are terminated, the greatest TPD (delay time) occurs and all
outputs display about the same 10 − 20 ps increase in TPD, so the
relative skew between any two output pairs remains about 25 ns.
For more information on using PECL, designers should refer to
ON Semiconductor Application Note AN1406/D.
The V_BB pin, an internally generated voltage supply, is available to
this device only. For single-ended input conditions, the unused
differential input is connected to V_BB as a switching reference voltage.
V_BB may also rebias AC coupled inputs. When used, decouple V_BB
and V_CC via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, V_BB should be left open.
