DTE vs. DCE Operation
Figure 15 shows a DCE or DTE controller-selectable
interface. The DCE/
DTE
pin (pin 14) switches the port
’
s
mode of operation. A logic HIGH selects DCE, which
enables D3 on the MAX3170, D3 on the MAX3171/
MAX3173, and D4 on the MAX3172/MAX3174. A logic
LOW selects DTE, which enables R1 on the MAX3170,
R1 on the MAX3171/MAX3173, and R4 on the MAX3172/
MAX3174.
This application requires only one DB-25 connector,
but separate cables for DCE or DTE signal routing. See
Figure 15 for complete signal routing in DCE and DTE
modes. For example, the MAX3170
’
s
D3 routes the TXC
(DCE) signal to pins 12 and 15 in DCE mode, while in
DTE mode, the MAX3170
’
s
R1 routes pins 12 and 15 to
TXC (DTE).
Complete Multiprotocol X.21 Interface
A complete DTE-to-DCE interface operating in X.21
mode is shown in Figure 16. The MAX3170 is used to
generate the clock and data signals, and the
MAX3171/MAX3173 generate the control signals. The
MAX3172/MAX3174 generate local loopback (LL), and
are used to terminate the clock and data signals to
support the V.11 protocol for cable termination. The
control signals do not need external termination.
Compliance Testing
A European Standard EN 45001 test report is available
for the MAX3170/MAX3171/MAX3173/MAX3172/
MAX3174 chipset. A copy of the test report will be
available from Maxim upon completion.
