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 Combination Table, 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 SN65LVDS31-33EVM includes the SN65LVDS31 quad driver and the SN65LVDS33 quad receiver. The SN65LVDS33 is a TIA/EIA-644 standard compliant LVDS receiver. The SN65LVDS33 receiver incorporates an enhanced common-mode input voltage range of -4 V to 5 V, as well as an
active-failsafe circuit that provides operation over the entire input common-mode range. The receiver provides an input voltage range specification compatible with a 5-V PECL signal.
