NB100LVEP91
2.5 V/3.3 V Any Level
Positive Input to
-2.5 V/-3.3 V LVNECL
Output Translator
Description
The NB100LVEP91 is a triple any level positive input to NECL
output translator. The device accepts LVPECL, LVTTL, LVCMOS,
HSTL, CML or LVDS signals, and translates them to differential
LVNECL output signals (−2.5 V / −3.3 V).
To accomplish the level translation the LVEP91 requires three
power rails. The V_CC pins should be connected to the positive power
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. These conditions will force the
Q outputs to a low state, and Q outputs to a high state, which will
ensure 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.
