MC100LVEL91
3.3 V Triple LVPECL Input to
−3.3 V to −5.0 V ECL Output
Translator
Description
The MC100LVEL91 is a triple LVPECL input to ECL output
translator. The device receives low voltage differential PECL signals,
determined by the V
CC
supply level, and translates them to differential
−3.3
V to
−5.0
V ECL output signals.
To accomplish the level translation the LVEL91 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 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
CC
/2
and the D input will be pulled to GND. 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.
