MaxLinear SP337E Multiprotocol Transceiver

MaxLinear SP337E multiprotocol transceivers contain 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 SP337EB multiprotocol transceiver features a maximum data rate of 250kbps in RS-232 mode and a maximum data rate of 15Mbps in RS-485/422. The SP337EU features a maximum data rate of 1Mbps in RS-232 mode and a maximum data rate of 15Mbps in RS-485/422 mode. SP337E multiprotocol transceivers require only four 0.1µF capacitors for complete functionality.
