Micrel, Inc. 3V LVTTL-TO-DIFFERENTIAL LVPECL AND DIFFERENTIAL LVPECL-TO-LVTTL TRANSLATOR www.DataSheet4U.com Precision Edge SY89328L Precision Edge® SY89328L ® FEATURES s 3.3V ±10% power supply s Guaranteed AC parameters over temperature: fMAX > 275MHz (LVTTL) s < 2ns LVPECL-to-LVTTL propagation delay s < 600ps LVTTL-to-LVPECL propagation delay s Internal 75kΩ input pull-up and pull-down resistors s Industrial temperature range: –40°C to +85°C s Available in ultra-small 8-pin MLF™ (2mm × 2mm) package Precision Edge® DESCRIPTION The SY89328L is a differential LVPECL-to-LVTTL translator and an LVTTL-to-differential LVPECL translator in a single package. Because LVPECL (Positive ECL) levels are used, only +3.3V and ground are required. The SY89328L is functionally equivalent to the SY100EPT28L, but in an ultra-small 8-lead MLF™ package that features a 70% smaller footprint. This ultra-small package and the dual translation design of the SY89328L make it ideal for applications that are sending and receiving signals across a backplane.
