XRT4500
MULTIPROTOCOL SERIAL NETWORK INTERFACE IC
REV. 1.0.7

1.2
The XRT4500 contains the following functional
blocks.
The High-Speed Transceiver Block
The Handshaking/Control Transceiver Block
The Diagnostic Operation Indicator Transceiver
Block
The Control Block
THE SYSTEM ARCHITECTURE
Block Diagrams are located on page 1 and 2. The
figures illustrate how the eight receivers and transmitters
in the XRT4500 are grouped into the “High-Speed
Transceiver” Block, the “Handshaking/Control Trans-
ceiver” Block and the “Diagnostic Operation Indicator
Transceiver” Block.
The “Control” block permits the user to implement the
following configuration options in the XRT4500.
Select which Communication Interface Mode the
XRT4500 will operate in. (RS-252, V.36, etc.)
Configure the XRT4500 into either the DTE or the
DCE Mode.
Configure the XRT4500 to operate in a “Loop-back”
Mode.
Enable the “Echo-Clock” Mode.
Configure the XRT4500 into the “Latch” Mode.
Configure the XRT4500 into the “Register” Mode.
Configure the XRT4500 into either the “2-Clock” or
the “3-Clock” Mode.
Enable the “Internal Oscillator”, in order to support
“Stand-Alone DTE Diagnostic Operation.
Invert the TXC Clock signal (for DCE Application) or
the RXC Clock signal (for DTE Applications).
Invert the TXD signal (for DTE Applications) or the
RXD signal (for DCE Applications).
Enable the X.21 mode.
A more detailed discussion of the “Control” Block can
be found in Section 1.2.4.
Figure 12, Figure 13, Figure 14, and Figure 15 are a
set of functional block diagrams that give more de-
tailed information about the four functional blocks
shown in the top-level diagram. Figure 12 presents
detailed information on the “High-Speed Transceiver”
block. Figure 13 presents detailed information about
the “Handshaking/Control Transceiver” block.
Figure 14 presents detailed information about the “Di-
agnostic Operation Indicator Transceiver” Block. Fi-
nally, Figure 15 presents some detailed information
about the “Control” Block.
