The MC100LVEL17 is a low-voltage, quad differential receiver. The device is functionally equivalent to the E116 device with the capability of operation from either a 3.3V or +3.3V supply voltage. The MC100EL17 is pin and functionally equivalent to the MC100LVEL17, but is specified for operation at the standard 100E ECL voltage supply. The LVEL17 provides a VBB output for either single-ended use or as a DC bias for AC coupling to the device. The VBB pin should be used only as a bias for the LVEL17 as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to ground via a 0.01f capacitor.
