If you double the clock rate (double the operating frequency), the bandwidth capacity doubles. If the operating frequency of the TDM bus is not provided but the number of time slots is known, the bandwidth of a TDM bus can be calculated by multiplying the number of time slots (as determined by the system clock rate) by 64 Kbps (the number of transmitted bits per communications channel). 048 Mbps (32 ϫ 64 Kbps ). 64 Mbps (512 time slots ϫ 64 Kbps). It is usually awkward to refer to the TDM bus bandwidth by the exact transmission capacity, so it is common to see the TDM bus bandwidth written, and referred to, as a 32-Mbps TDM bus.
