(100KEP) ECL/LVECL DC ELECTRICAL CHARACTERISTICS(1)
VCC = 0V, VEE = –5.5V to –3.0V
Notes:
1. 100KEP circuits are designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. The circuit is in
a test socket or mounted on a printed circuit board and traverse airflow greater than 500lfpm is maintained.
2. The V
IHCMR range is referenced to the most positive side of the differential input signal.

AC ELECTRICAL CHARACTERISTICS
VCC = 0V; VEE = –3.0V to –5.5V or VCC = 3.0V to 5.5V, VEE = 0V
Notes:
1. Measured with 750mV input signal, 50% duty cycle. Output swing ≥400mV. All loading with a 50 to VCC –2.0V.
2. Skew is measured between outputs under identical transitions. Duty cycle skew is defined only for differential operation when the delays are
measured from the cross point of the inputs to the cross point of the outputs.
3. RJ is measured with a K28.7 comma detect character pattern, measured at 1.25Gbps and 2.5Gbps.
4. DJ is measured at 1.25Gbps and 2.5Gbps, with both K28.5 and 223–1 PRBS pattern.
