Product Overview MC100LVEL90: Translator, Triple ECL Input to LVPECL Output For complete documentation, see the data sheet Product 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 VEE 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 VCC supply should be connected to the positive supply, and the VEE pin should be connected to the negative power supply. The GND pins, as expected, are connected to the system ground plane. Both VEE and VCC should be bypassed to ground via 0.015F capacitors. Under open input conditions, the Dbar input will be biased at VEE/2 and the D input will be pulled to VEE . This condition will force the Q output 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. BB may also rebias AC coupled inputs. When used, decouple VBB and VCC via a 0.01 5F capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open.
