General Description
The MXL1544/MAX3175 are four-driver/four-receiver
multiprotocol transceivers that operate from a single
+5V supply in conjunction with the MXL1543. The
MXL1544/MAX3175, along with the MXL1543 and
MXL1344A, form a complete software-selectable data
terminal equipment (DTE) or data communication
equipment (DCE) interface port that supports the V.28
(RS-232), V.10/V.11 (RS-449/V.36, EIA-530, EIA-530A,
X.21, RS-423), and V.35 protocols. The MXL1544/
MAX3175 transceivers carry serial interface control sig-
naling, while the MXL1543 carries the high-speed clock
and data signals. Typically, the MXL1543 is terminated
using the MXL1344A. The MAX3175 is identical to the
MXL1544 except for the addition of a 10s (typ) glitch
rejection circuit at the receiver inputs. The MXL1544/
MAX3175 are available in 28-pin SSOP packages.
