TEXAS INSTRUMENTS SN65HVD22EVM 评估模块, SN65HVD2X, RS485发送收发器, 高静电防护保护, 宽接收器滞后
The is an evaluation module will allow designers to develop and analyze data transmission systems using the SN65HVD2x family from "s. This series of devices, including the SN65HVD20, SN65HVD21, SN65HVD22, SN65HVD23 and SN65HVD24, comply with TIA/EIA-485. Also, these devices use the industry standard 176 and 180 footprint, allowing standard devices such as the SN75176 or SN75ALS180 to be installed onto the evaluation module. The HVD22EVM has the SN65HVD22 transceiver installed on the evaluation module, however other SN65HVD2x devices can be sampled and be added to the evaluation module PWB. The evaluation module can be used to evaluate device parameters while acting as a guide for board layout. The board allows for the connection of a 100ohm controlled impedance cable of varying lengths. This provides the designer with a functional tool for his circuit evaluation that will facilitate the successful first pass design of an end product.
