MAX14840PMB1 Peripheral Module
General Description
The MAX14840PMB1 peripheral module provides the
necessary hardware to interface the MAX14840E RS-485
transceiver to any system that utilizes Pmod^TM-compatible
expansion ports configurable for a UART interface. The
IC is a +3.3V ESD-protected transceiver intended for
half-duplex RS-485 communication up to 40Mbps*. These
transceivers are optimized for high speeds over extended
cable runs, while maximizing tolerance to noise.
The IC features symmetrical fail-safe and larger receiver
hysteresis, providing improved noise rejection and
improved recovered signals in high-speed and long-
cable applications.
*The maximum communication speed of this module
is generally less than 10Mbps due to the presence of
current-limiting resistors on the data lines of this module
and possibly also the host board.
Refer to the MAX14840E IC data sheet for detailed infor-
mation regarding operation of the IC.
