TI offers a series of low-voltage differential signaling (LVDS) evaluation modules (EVMs) designed for anlysis 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 SN65LVDS31-32EVM includes the SV65LVDS31 quad driver and the SN65LVDS32 quad receiver. The SN65LVDS31 is a TIA/EIA-644 standard-compliant LVDS driver. The SN65LVDS32 is a TIA/EIA-644 standard-compliant receiver, which incorporates a passive open-circuit failsafe detection circuit. The failsafe circuit included in the SN65LVDS32 includes a pair of 300-K ohm pull-up resistors on the bus pins.
Note: This tool is replacing the SN65LVDS31/32A.
