Description
AI
The MC100LVEL92 is a triple PECL input to LVPECL output translator. The device receives standard PECL signals and translates them to differential LVPECL output signals.To accomplish the PECL to LVPECL level translation, the MC100LVEL92 requires three power rails. The VCC supply is to be connected to the standard 5 V PECL supply, the LVCC supply is to be connected to the 3.3 V LVPECL supply, and Ground is connected to the system ground plane. Both the VCCand LVCC should be bypassed to ground with 0.01 F capacitors.The PECL VBBpin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to VBBas a switching reference voltage. VBBmay also rebias AC coupled inputs. When used, decouple VBBand VCCvia a 0.01 F capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBBshould be left open.
