Micrel, Inc. 5V/3.3V TTL-TO-DIFFERENTIAL PECL TRANSLATOR Precision Edge® SY10ELT20V Precision Edge® SY100ELT20V SY10ELT20V SY100ELT20V FEATURES ■ ■ ■ ■ ■ ■ ■ 3.3V and 5V power supply options 300ps typical propagation delay Low power Differential PECL output PNP TTL input for minimal loading Flow-through pinouts Available in 8-pin SOIC package and in die form Precision Edge® DESCRIPTION The SY10/100ELT20V is a single TTL-to-differential PECL translator. Because PECL (Positive ECL) levels are used, either +5V or +3.3V and ground are required. The small outline 8-lead SOIC package and low skew single gate design make the ELT20V ideal for applications that require the translation of a clock or data signal where minimal space, low power, and low cost are critical. The ELT20V 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.
