Precision Edge SY10ELT20V Precision Edge Micrel, Inc. SY100ELT20V 5V/3.3V TTL-TO-DIFFERENTIAL SY10ELT20V PECL TRANSLATOR SY100ELT20V FEATURES 3.3V and 5V power supply options Precision Edge 300ps typical propagation delay Low power DESCRIPTION Differential PECL output PNP TTL input for minimal loading The SY10/100ELT20V is a single TTL-to-differential Flow-through pinouts PECL translator. Because PECL (Positive ECL) levels Available in 8-pin SOIC package and in die form 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.
