Order Number: 304120

5.1.3

AdvancedTCA Data Transport Connector (J20)

The MPCBL0010 SBC implementation of the telecom clock uses the J20 connector to

connect to the three separate and redundant clock buses on the AdvancedTCA

backplane. The Zone 2 J20 connector consists of one 120-pin HM-ZD connector with 40

differential pairs.

5.1.4

Alignment Blocks

The MPCBL0010 SBC implements the K1 and K2 alignment blocks at the top of Zone 2

and Zone 3, as required in Section 2.4.4 of the PICMG 3.0 specification. The Zone 2

alignment block is assigned a keying value of 11, and uses a Tyco* 1469373 or a Tyco

1469268 component (or equivalent). The Zone 3 alignment block has a solid face and is

used to ensure that rear transition modules (RTMs) with protruding connectors are not

plugged into the MPCBL0010 SBC or vice versa; the component used for this is either a

Tyco 1469374 or a Tyco 1469275-2 (or equivalent).
