NOTES:
THE SPLIT-LOAD TERMINATIONS FOR ECL SIGNALS NEED TO BE LOCATED AT THE INPUT
OF DEVICES RECEIVING THOSE ECL SIGNALS. RECOMMEND 4-LAYER PRINTED CIRCUIT
BOARD WITH 50 OHM MICROSTRIP SIGNAL PATHS BE USED.
R1 = R4 = R6 = R8 = R10 = 130 OHMS FOR +5.0 V OPERATION, 82 OHMS FOR +3.3 V OPERATION.
R2 = R3 = R5 = R7 = R9 = 82 OHMS FOR +5.0 V OPERATION, 130 OHMS FOR +3.3 V OPERATION.
C1 = C2 = C3 = C5 = C6 = 0.1 μF.
C4 = 10 μF.
L1 = L2 = 1 μH COIL OR FERRITE INDUCTOR.
