LOW SKEW, 1-TO-18 LVPECL-TO-LVCMOS/LVTTL FANOUT BUFFER

AC Electrical Characteristics

Table 5A. AC Characteristics, VDD =VDDO = 3.3V ± 5%, TA = -40°C to 85°C

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: All parameters measured at 200MHz unless noted otherwise.

NOTE 1: Measured from the differential input crossing point to the output VDDO/2.

NOTE 2: Measured from VDD/2 to VDDO/2.

NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDDO/2.

NOTE 4: Defined as skew between outputs on different devices operating at the same supply voltage, same temperature and with equal load

conditions. Using the same type of inputs on each device, the outputs are measured at VDDO/2.

NOTE 5: This parameter is defined in accordance with JEDEC Standard 65.

NOTE 6: Defined as skew between outputs on different devices, across temperature and voltage ranges, and with equal load conditions. Using

the same type of inputs on each device, the outputs are measured at VDDO/2.
