SHB
SHB Connector
The SMT398 includes 4 60-pin connectors to provide SHB communication to the
outside world.
The connectors are referenced on the PCB by J8, J9, J10 and J11 (See Figure
19:SMT398 Components placement-Top view ).
All 60 pins of a SHB connector are routed to a Virtex II 3000 and above in SMT398
Full configuration .
SMT398s with a smaller Virtex II (1000 to 2000) only provide access to 25 pins per
SHB Connector in
Basic configuration , which represents the minimum amount
required to implement 1 Half Word Interface (Hw). (See SUNDANCE SHB
specification and Sundance SDB specification. )
