1 SY100EL90V micrel, inc. m9999-031306 hbwhelp@micrel.com or (408) 955-1690 description 3.3v and 5v power supply options 500ps propagation delay fully differential design supports both standard and low voltage operation available in 20-pin soic package the SY100EL90V is a triple ecl/lvecl-to-pecl/ lvpecl translator. the device can translate over all combinations of supply voltages: -5v ecl to 5v pecl, -5v ecl to 3.3v lvpecl, -3.3v lvecl to 5v pecl or -3.3v lvecl to 3.3v lvpecl. a v bb output is provided for interfacing with single ended ecl signals at the input. if a single ended input is to be used, the v bb output should be connected to the d input. the active signal would then drive the d input. when used, the v bb output should be bypassed to via a 0.01 f capacitor. the v bb output is designed to act as the switching reference for the el90v under single ended input switching conditions. as a result this pin can only source/sink up to 0.5ma of current. to accomplish the level translation the el90v requires three power rails. the v cc supply should be connected to the positive supply, and the v ee pin should be connected to the negative power supply. the gnd pins as expected are connected to the system ground plane. both v ee and v cc should be bypassed to ground via 0.01 f capacitors. under open input conditions, the d input will be biased at v cc /2 and the d input will be pulled to v ee . this condition will force the q output to a low, ensuring stability. features 5v/3.3v triple ecl/lvecl-to- pecl/lvpecl translator pin function dn ecl/lvecl inputs q n pecl/lvpecl outputs v bb ecl/lvecl reference voltage output SY100EL90V pin names function table function v cc gnd v ee ?v ecl to 5v pecl 5v 0v ?v ?v ecl to 3.3v lvpecl 3.3v 0v ?v ?.3v lvecl to 5v pecl 5v 0v ?.3v ?.3v lvecl to 3.3v lvpecl 3.3v 0v ?.3v 1 rev.: i amendment: /0 isse date: march 2006
