GENERAL DESCRIPTION
The XRT4000 is a fully integrated multiprotocol serial
interface. It is a universal device because it supports
all of the popular serial physical interfaces such as
V.35, V.36, EIA-530 (A), RS232 (V.28), X.21 and
RS449. Furthermore it can easily be interfaced with
most common types of HDLC controllers. This
device contains 8 receivers and 8 transmitters. It is
a complete solution containing all of the required
source and load terminations in one 100 pin TQFP
package.
XRT4000 can be configured to operate in one of the
seven interfaces in either DTE and DCE modes of
operation and power down mode. It fully supports
echoed clock as well as clock and data inversion. An
elaborate set of loopbacks are supported in DTE and
DCE modes of operation. This eliminates the need
for external circuitry for loopback implementation.
The control signals such as RI, RL, DCD, DTR, DSR
are protected against glitches by internal filters.
These filters can be disabled. XRT4000 has an
internal oscillator which is used to create a clock
signal needed to conduct standalone diagnostics of
DTE equipment.
