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.
