SMT376 User Manual

SDB

The SMT376 provides two Sundance Digital Buses (SDBs). These 16-bit data
parallel links for synchronous transmission can achieve high-speed data transfer
across 40-way flat ribbon cables with ground-interlaced 3.3v signals (Ref. SMT3xx-
SDB-CAB) and Samtec QSH/QTH based cable designs.
The SDB connector carries one 16 bits SDB bus (SDB0).
The SHB connector carries one 16 bits SDB bus (SDB1). The second 16 SDB is not
implemented.
See general firmware description

SDB Clock selection
In this firmware the SDB clock is not selectable and is fixed at 100MHz.
Changing the bit SDBCLK will have no effect

Global bus

The SMT335 provides one global bus interface.
