Connection Between CX28500 and Other TSBUS Device
1
This section details the signals required to implement the TSBUS
Interface. The CX28500 implements a subset of
this bus.
Figure E-1
illustrates the TSBUS connections between the other device and CX28500. The signals
required are summarized in
Tables E-1
and E-2. The TSBUS consists of the Payload and the Overhead bus. Each
bus has a Transmit and Receive path. The receive path is defined from the other device to CX28500, and the
transmit path is defined from CX28500 to the other device.
Note that while the bus defines the TSB_RSYNCI, TSB_TSYNCI and TSB_TSYNCO pins, these are absent from
the CX28500, and thus a CX28500 implements only a subset of the TSBUS standard. See the documentation of
the CX29503 or CX28560 parts for more complete explanation of the TSBUS standard.
Figure E-1
illustrates the CX28500 pin definitions in TSBUS mode.
