3.3V Differential LVPECL/LVDS/CML to LVTTL/LVCMOS Translator

The MC100EPT21 is a Differential LVPECL/LVDS/CML to LVTTL/LVCMOS translator. Because LVPECL (Positive ECL), LVDS, and positive CML input levels and LVTTL/LVCMOS output levels are used, only +3.3 V and ground are required. The small outline 8?lead SOIC package makes the EPT21 ideal for applications which require the translation of a clock or data signal.

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 0.01 μF capacitor. For additional information see AND8020/D. 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.
