NOT RECOMMENDED FOR NEW DESIGNS 3.3V, DUAL DIFFERENTIAL LVPECL-TO-LVTTL TRANSLATOR Precision Edge® PrecSiYsi1o0SnSYEY1EL01dT00EEg2LL3eTTL®2233LL SY100ELT23L FEATURES s 3.3V power supply s 2.0ns typical propagation delay s <500ps typical output-to-output skew s Differential LVPECL inputs s 24mA LVTTL outputs s Flow-through pinouts s Available in 8-pin SOIC package Precision Edge® DESCRIPTION The SY10/100ELT23L are dual differential LVPECLto-LVTTL translators with +3.3V power supply. Because LVPECL (Low Voltage Positive ECL) levels are used, only +3.3V and ground are required. The small outline 8pin SOIC package and the low skew, dual gate design of the ELT23L makes it ideal for applications which require the translation of a clock and a data signal. The ELT23L is available in both ECL standards: the 10ELT is compatible with positive ECL 10H logic levels, while the 100ELT is compatible with positive ECL 100K logic levels.
