ICS853S004I Data Sheet

LOW SKEW, 1-TO-4, DIFFERENTIAL-TO-2.5V, 3.3V LVPECL/ECL FANOUT BUFFER

AC Electrical Characteristics

NOTE: All parameters are measured at f

 1GHz, unless otherwise noted.

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device

is mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal

equilibrium has been reached under these conditions.

NOTE 1: Measured from the differential input crossing point to the differential output crossing point.

NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.

Measured at the output differential cross points.

NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltage, same frequency, same temperature and

with equal load conditions. Using the same type of inputs on each device, the outputs are measured at the differential cross points.

NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
