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.

R2 = R3 = R5 = R7 = R9 = 82 OHMS.

C1 = C2 = C3 = C5 = C6 = 0.1 µF.

C4 = 10 µF.

L1 = L2 = 1 µH COIL OR FERRITE INDUCTOR.

ESD damage during shipment or

storage.

with these parts. It is further

recommended that a contiguous

ground plane be provided in the

circuit board directly under the

transceiver to provide a low

inductance ground for signal

return current. This recommen-

dation is in keeping with good

high frequency board layout

practices.

Board Layout - Hole Pattern

The Agilent transceiver complies

with the circuit board “Common

Transceiver Footprint” hole

pattern defined in the original

multisource announcement which

defined the 1x9 package style.

This drawing is reproduced in

Figure 8 with the addition of ANSI

Y14.5M compliant dimensioning

to be used as a guide in the

mechanical layout of your circuit

board.

Board Layout - Decoupling

Circuit and Ground Planes

It is important to take care in the

layout of your circuit board to

achieve optimum performance

from these transceivers. Figure 7

provides a good example of a

schematic for a power supply

decoupling circuit that works well
