Overview
The MC100EPT21DTG, produced by onsemi, is a 3.3V Differential LVPECL/LVDS/CML to LVTTL/LVCMOS translator. This device is designed to translate clock or data signals from LVPECL, LVDS, or CML input levels to LVTTL/LVCMOS output levels, requiring only a +3.3V power supply and ground. The small outline 8-lead TSSOP package makes it ideal for applications where space is limited. The device includes a VBB output that allows for cap-coupled single-ended or differential input configurations, enhancing its versatility in various signal translation scenarios.
