ATM Transceivers for SONET OC-3 / SDH STM-1 in Low Cost 1 x 9 Package Style

Avago Technologies 

Board Layout - Hole Pattern

The Avago Technologies transceiver complies with the

circuit board “Common Transceiver Footprint” hole

pattern defined in the original multisource announce-

ment which defined the 1 x 9 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 - Mechanical

For applications interested in providing a choice of either

a duplex SC or a duplex ST connector interface, while uti-

lizing the same pinout on the printed circuit board, the ST

port needs to protrude from the chassis panel a minimum

of 9.53 mm for sufficient clearance to install the ST con-

nector.

Please refer to Figure 8a for a mechanical layout detailing

the recommended location of the duplex SC and duplex

ST transceiver packages in relation to the chassis panel.
