ICS853S024 Data Sheet

LOW SKEW, 1-TO-24, DIFFERENTIAL-TO-3.3V, 2.5V LVPECL FANOUT BUFFER

Table 3D. LVPECL DC Characteristics, VCC = 2.5V ± 5%, VEE = 0V, TA = 0°C to 70°C

NOTE 1: All outputs are terminated with 50

Ω to V

CC – 2V.

AC Electrical Characteristics

Table 4. AC Characteristics, VCC = 3.3V ± 5% or 2.5V ± 5%, VEE = 0V, TA = 0°C to 70°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 are measured at fOUT ≤ 1GHz, unless otherwise noted.

NOTE: Special thermal considerations may be required. See Applications Section.

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

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

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