Sundance Digital Bus  (SDB)

The SDB is a high-speed 16-bit communications device. The DSP accesses this device 32 bits at a time. Such accesses are presented at the connector as pairs of 16-bit accesses.

The SDB is present on many TIMs, but has been superseded by the SHB.  

An SDB connector is shown below. For a photo of the SDB cable see this section.
