0 GENERAL DESCRIPTION The SP337E is a dual mode serial transceiver containing both RS-232 and RS-485/422 line drivers and receivers.
The RS-232 mode provides three drivers and five receivers to support all eight signals commonly used in the DB9 serial port connector (3TX/5RX).
In RS-485 mode the device features two independent high speed RS-485/422 transmit and receive channels (2TX/2RX).
The default RS-485 configuration is full-duplex, but half-duplex operation can be obtained by tying together the TX and RI pins, and the TXEN and RXEN signals.
The SP337E is pin compatible to MaxLinear’s SP334.
The SP337EB features a maximum data rate of 250kbps in RS-232 mode and a maximum data rat e of 15Mbps in RS-485.
However, the SP337EU features a maximum data rate of 1Mbps in RS-232 mode and a maximum data rate of 15Mbps in RS-485 mode.
The MaxLinear-patented high efficiency charge pumps (5,306,954) deliver true RS-232 driver out put voltages from a single power supply from 3.
3V to 5V.
Charge pump outputs are self-monitored to minimize power consumption.
The SP337E requires only four 0.
1µF capacitors for complete functionality.
All RS-485 receivers or transceivers feature high impedance inputs which allow up to 256 transceivers on a single shared bus.
When configured in RS -485 mode, each driver may be individually enabled or put into tri-state, simplifying use on shared bus es or for bidirectional communication.
The RS-485/422 drivers can be disabled (high-Z output) by the TXEN enabl e pin.
The RS-232 receiver outputs can be disabled by the RXEN enable pin.
All receivers have advanced failsafe protection to prevent oscillation when inputs are un-connected.
In RS-232 mode, each receiver input has a 5kΩ pulldown to ground.
in RS-485 mode, receivers will default to output logic 1 if inputs are floating, shorted, or open but terminated.
All driver outputs and receiver inputs are protected...
