SY100EPT28L

SY100EPT28L 3.3V LVTTL-to-Differential LVPECL and Differential LVPECL-to-LVTTL Translator Features 3.3V ±10% Power Supply Guaranteed AC Parameters over Temperature: fMAX > 275 MHz (LVTTL) <2.5 ns LVPECL-to-LVTTL Propagation Delay <600 ps LVTTL-to-LVPECL Propagation Delay Industrial Temperature Range: –40°C to +85°C Available in 8-Lead MSOP and SOIC packages General Description The SY100EPT28L 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 small outline 8-pin package and the dual translation design of the EPT28L makes it ideal for applications that are sending and receiving signals across a backplane. Under open input conditions, the /D_LVPECL input will be biased at VCC/2 and the D_LVPECL input will be pulled to GND. This condition will force the Q_LVTTL to a low, ensuring stability. The 100k series includes temperature compensation. Thus, logic levels are constant over temperature.
