Low Voltage Dual 1:4, 1:5
Differential Fanout Buffer

ECL/PECL Compatible

The MC100LVE210 is a low voltage, low skew dual differential
ECL fanout buffer designed with clock distribution in mind. The
device features two fanout buffers, a 1:4 and a 1:5 buffer, on a single
chip. The device features fully differential clock paths to minimize
both device and system skew. The dual buf fer allows for the fanout of
two signals through a single chip, thus reducing the skew between the
two fundamental signals from a part–to–part skew down to an
output–to–output skew . This capability reduces the skew by a factor of
4 as compared to using two LVE111’s to accomplish the same task.
The MC100LVE210 works from a –3.3V supply while the
MC100E210 provides identical function and performance from a
standard –4.5V 100E voltage supply .

For applications which require a single–ended input, the V

BB

reference voltage is supplied. For single–ended input applications the
VBB reference should be connected to the unused CLK input of a
differential pair and bypassed to ground via a 0.01µf capacitor. The
input signal is then driven into the selected CLK input.

T o ensure that the tight skew specification is met it is necessary that
both sides of the differential output are identically terminated, even if
only one side is being used. In most applications all nine differential
pairs will be used and therefore terminated. In the case where fewer
than nine pairs are used it is necessary to terminate at least the output
pairs adjacent to the output pair being used in order to maintain
minimum skew. Failure to follow this guideline will result in small
degradations of propagation delay (on the order of 10–20ps) of the
outputs being used, while not catastrophic to most designs this will
result in an increase in skew. Note that the package corners isolate
outputs from one another such that the guideline expressed above
holds only for outputs on the same side of the package.

The MC100LVE210, as with most ECL devices, can be operated
from a positive VCC supply in PECL mode. This allows the L VE210 to
be used for high performance clock distribution in +3.3V systems.
Designers can take advantage of the LVE210’s performance to
distribute low skew clocks across the backplane or the board. In a
PECL environment series or Thevenin line terminations are typically
used as they require no additional power supplies, if parallel
termination is desired a terminating voltage of VCC–2.0V will need to
be provided. For more information on using PECL, designers should
refer to Application Note AN1406/D.
