SHB Cable Assembly
The cable is custom made by Precision Interconnect and a cable assembly solution
builder can be found at:
SHB Inter Modules solutions
High-speed data transfer can be achieved between TIM modules thanks to the use of
a 60-way flat ribbon micro-coax cable or via PCB connections.
InterModule PCBs can be found at:
As a result, NO DIFFERENTIAL lines are required to transfer data on long distances
and at speeds in excess of 100Mhz, which allows the full use of the SHB connector
60 pins.
SHB 16-bit Interface
The SHB connectors provide to the FPGA connections to the external world.
You can implement your own interface to transfer data over using these connectors,
but if you want to communicate with other Sundance TIM modules, you can
implement a 16-bit SHB interface sitting on 25 pins of an SHB connector.
Then, the SHBs are parallel communication links for synchronous transmission.
The SHB interface is derived from the SDB interface which is a 16-bit wide
synchronous communication
The differences are:
The SHB interface can be 8, 16 or 32-bit wide.
The transfer rates are at least doubled.
As an example, let us consider the 16-bit SHB interface.
You can implement 2 SHB interfaces as per Table 8 per SHB connector. (no
differential lines are needed thanks to our SHB cable assembly described in 0.
The SMT398 in full configuration (0 Full configuration) provides 8 16-bit Sundance High
Speed Buses (SHB) on 4 connectors and can support data rates of up to 200MHz.
Each SHB interface is 16-bits wide and so, by running 4 buses together, a data rate
of 1.6Gbytes/s is achieved.
You must refer to the latest
on how it works.
