Digital Cerebus System Hardware
The Digital Cerebus System is compatible with the whole family of the Blackrock CerePlex digital
headstages. Blackrock digital headstages enable low noise transmission in a minimally invasive package.
The output of the CerePlex digital headstages are multiplexed, meaning that only a reduced set of wires
are needed to transmit the already digitized data from all the input channels. The following block diagram
depicts the different components and their roles within a Digital Cerebus System.
Digital Hub 128
The Blackrock Digital Hub provides an interface between the NSP and CerePlex digital
headstages. The Digital Hub converts digital signal to an optic-digital format which is sent directly
to the NSP. This dramatically reduces the noise introduced to the signal during transmission. The
Digital Hub can handle many possible configurations when it is connected to multiple CerePlex
digital headstages provided that the total number of channels does not exceed maximum 128
channels.
