Positive Input to −2.5V /
−3.3V / −5V NECL Output
Translator
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
NECL output signals (-2.5 V / -3.3 V / -5 V).
To accomplish the level translation the LVEP91 requires three
power rails. The VCC supply should be connected to the positive
supply, and the VEE pin should be connected to the negative power
supply. The GND pins are connected to the system ground plane. Both
VEE and VCC should be bypassed to ground via 0.01 mF capacitors.
Under open input conditions, the D input will be biased at VCC/2
and the D input will be pulled to GND. These conditions will force the
Q outputs to a low, ensuring stability.
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.
• Typical Maximum Frequency > 2.0 GHz
• 430 ps Typical Propagation Delay
• Operating Range: VCC = 2.375 V to 3.8 V;
VEE = -2.375 V to -5.5 V; GND = 0 V
• Q Output will Default LOW with Inputs Open or at GND
