The MC100LVEL32 is an integrated 2 divider. The differential clock inputs and the VBB allow a differential, single-ended or AC coupled interface to the device. If used, the VBB output should be bypassed to ground with a 0.01F capacitor. Also note that the VBB is designed to be used as an input bias on the LVEL32 only, the VBB output has limited current sink and source capability.The LVEL32 is functionally identical to the EL32, but operates from a low voltage supply.
