Micrel, Inc. ECL Pro™ SY100EPT23L ECL Pro™ 3.3V DUAL DIFFERENTIAL LVPECL-to-LVTTL TRANSLATOR SY100EPT23L FEATURES ■ ■ ■ ■ ■ ■ ■ 3.3V power supply 1.9ns typical propagation delay Maximum frequency > 275MHz Differential LVPECL inputs 24mA LVTTL outputs Flow-through pinouts Internal input resistors: pulldown on D, pulldown and pullup on /D ■ Q output will default LOW with inputs open or at Ground ■ Available in 8-pin MSOP and SOIC packages ECL Pro™ DESCRIPTION The SY100EPT23L is a dual differential LVPECL-toLVTTL translator. Because LVPECL (Low Voltage Positive ECL) levels are used, only +3.3V and ground are required. The tiny 8-pin MSOP and dual-gate design of the EPT23L makes it ideal for applications which require the translation of a clock and data signal. The EPT23L is available in only the ECL 100K standard. Since there are no LVPECL outputs or an external VBB reference, the EPT23L does not require both ECL standard versions. The inputs can accept 10K voltage levels and any standard differential LVPECL input referenced from a VCC of +3.3V PIN NAMES Pin Function Q0, Q1 LVTTL Outputs D0, /D0, D1, /D1 Differential LVPECL Inputs VCC Positive Supply GND Ground ECL Pro is a trademark of Micrel, Inc.
