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