The SN65HVD22EVM evaluation module (EVM) helps you develop and analyze data transmission systems using our SN65HVD2x family of devices. This series of devices, including the SN65HVD20, SN65HVD21, SN65HVD22, SN65HVD23 and SN65HVD24, complies with TIA/EIA-485. These devices also use the industry standard 176 and 180 footprint, allowing standard devices such as the SN75176 or SN75ALS180 to be installed onto the EVM. The SN65HVD22EVM has the SN65HVD22 transceiver installed on the EVM, however other SN65HVD2x devices can be sampled and be added to the EVM PWB. This EVM lets you quickly, easily and accurately evaluate our SN65HVD2x family of RS-485 products. The PWB also facilitates different medium interconnections and the use of various transmission topologies.

The EVM can be used to evaluate device parameters while acting as a guide for board layout. The board allows for the connection of a 100-Ω 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.

  • Hardware: SN65HVD22 EVM PWB
  • Screw-type SMA jacks and Bergstik headers serve as the I/O connections
  • Banana jacks serve as the DC power input terminals
