MC100LVEL90/D
MC100LVEL90
−3.3V / −5VTriple ECL Input
to LVPECL Output Translator
Description
The MC100LVEL90 is a triple ECL to LVPECL translator. The device
receives either 3.3 V or 5 V differential ECL signals, determined by the
V
EE
supply level, and translates them to +3.3 V differential LVPECL
output signals.
To accomplish the level translation, the LVEL90 requires three power
rails. The V
CC
supply should be connected to the positive supply, and the
V
EE
pin should be connected to the negative power supply. The GND
pins, as expected, are connected to the system ground plane. Both V
EE
and V
CC
should be bypassed to ground via 0.01 mF capacitors.
Under open input conditions, the D input will be biased at V
EE
/2 and
the D input will be pulled to V
EE
. This condition will force the Q output
to a LOW, ensuring stability.
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.
