Exar SP337EBEY-0A-EB 工具套装
EXAR SP337EBEY-0A-EB Evaluation Board, Multiprotocol Transceiver TxRx, TSSOP, Full Duplex Configuration
EXAR
The SP337EBEY-0A-EB is an evaluation board for SP337E, a dual mode serial transceiver containing both RS 232 and RS 485 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/RS 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 SP337 is pin compatible to SP334. All receivers have advanced failsafe protection to prevent oscillation when inputs are un connected. In RS 232 mode, each receiver input has a 5kΩ pull down to ground. In RS 485 mode, receivers will default to output logic one if inputs are floating, shorted, or open but terminated. 3.3V or 5V supply voltage operation Software programmable RS 232 or RS 485/RS 422 selection Maximum data rate of 15Mbps in RS 485/RS 422 and up to 1Mbps in RS 232 mode (SP337EU) Three drivers, five receivers RS 232/V.28 Two drivers, two receivers RS 485/RS 422 Test point for cable or jumper loop back Robust ESD specifications Slew rate control feature, low EMI Full differential driver tri state (Hi-Z) control Receiver output tri state control All driver outputs and receiver inputs are protected against ESD strikes up to ±15,000 volts.
