MC10E411
5V ECL 1:9 Differential
PECL/NECL RAMBus Clock
Buffer
Description
The MC10E411 is a low skew 1-to-9 differential driver, designed
with clock distribution in mind. The MC10E411’s function and
performance are similar to the popular MC10E111, with the added
feature of 1.2 V output swings.
The output voltage swing of the E411 is larger than a standard ECL
swing. The 1.2 V output swings provide a signal which can be AC
coupled into RAMBus compatible input loads. The larger output
swings are produced by lowering the VOL of the device. With the
exception of the lower VOL, the E411 is identical to the MC10E111.
Note that the larger output swings eliminate the possibility of
temperature compensated outputs, thus the E411 is only available in
the 10E style of ECL. In addition, because the VOL is lower than
standard ECL, the outputs cannot be terminated to −2.0 V. This data
sheet provides a few termination alternatives.
The device TPD is affected by the quantity of output pairs
terminated with minimum occurring with only one output pair and
increasing about 10 − 20 ps for all output pairs. Relative skew
distribution is not affected as more pairs are terminated, but the
increased TPD does shift the entire distribution. Unused output pairs
should be left unterminated (open) to reduce power and switching
noise.
The VBB pin, an internally generated voltage supply, is available to
this device only. For single-ended input conditions, the unused
differential input is connected to VBB as a switching reference voltage.
VBB may also rebias AC coupled inputs. When used, decouple VBB
and VCC via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, VBB should be left open.
