The MC100EPT21DTG is a 3.3V Differential LVPECL/LVDS/CML to LVTTL/LVCMOS Translator ideal for applications which requires the translation of a clock or data signal. Because LVPECL (positive ECL), LVDS and positive CML input levels and LVTTL/LVCMOS output levels are used, only 3.3V and ground are required. The VBB output allows this EPT21 to be cap coupled in either single-ended or differential input mode. When single-ended cap coupled, VBB output is tied to the D input and D is driven for a non-inverting buffer or VBB output is tied to the D input and D is driven for an inverting buffer. When cap coupled differentially, VBB output is connected through a resistor to each input pin. If used, the VBB pin should be bypassed to VCC via a 0.01F capacitor. For a single-ended direct connection use an external voltage reference source such as a resistor divider. Do not use VBB for a single-ended direct connection or port to another device.
