UG-277 Datasheet, PDF (12/24 Pages) Analog Devices – SDP-B Controller Board

UG-277
The mating daughter board 120-pin connector is the Hirose
FX8-120S-SV(21), 120-pin receptacle, FEC 132-4660, Digi-Key
H1219-ND. Consult the connector's data sheet for full details
on the connector. Note that Pin 1 to Pin 60 are placed on the
left side of the connector and Pin 61 to Pin 120 are placed on
the right side of the connector.
Keep Out Area
In order to allow the greatest flexibility for future controller
boards, a keep out area is established for components higher
that 3 mm. The keep out area is 12.65 mm wide and extends
down the entire left side of the daughter board.
Restriction on Right Angle Connectors
Due to the close proximity of the edges of the A and B daughter
boards (seen in Figure 4) right angle connectors are not allowed

on the top and left edges of the daughter boards and (if
required) should be placed on the right or bottom edges. The
phrase "right angle connector" is used to describe any connector
that requires the connection to protrude over the edge of the
board (for example, right angle SMB or screw terminal)
MECHANICAL SPECIFICATIONS
The mechanical specifications of the SDP-B board are 2.75" ×
2.25" (69.85 mm × 27.15 mm). The height of the 120-pin con-
nectors from the bottom of the board is approximately 0.152"
(3.86 mm). The tallest component on the top is approximately
0.125" (3.175 mm), and the tallest components on the bottoms
are the connectors at approximately 0.152" (3.86 mm). Refer to
