TI offers a series of low-voltage differential signaling (LVDS) evaluation modules (EVMs) designed for analysis of the electrical characteristics of LVDS drivers and receivers. Four unique EVMs are available to evaluate the different classes of LVDS devices offered by TI.
As seen in the table above, various combinations of drivers and receivers are supported by the different EVMs. Both drivers shown in the table are pin-compatible, as are the three receivers. The same printed circuit board (PCB) has been used for all four EVMs, resulting in the same operating instructions included herein.
The SN65LVDM31-32BEVM includes the SN65LVDM31 quad driver and SN65LVDS32B quad receiver. The SN65LVDM31 is a multipoint LVDS driver that provides twice the drive strength of standard LVDS compliant drivers to allow operation in doubly-terminated topologies, heavily loaded bus lines, or situations where increased noise margin is desired in a design. The SN65LVDM31 complies with the driver requirements of the TIA/EIA-644 standard, except for doubling of the output current.
