Technical Note
âOperation Control
MSDL3 Channel Count Selection
Pin LS is used to control the high-speed data channel count and data format. The LS pin settings (i.e., high-speed data
channel count, data format) should be the same between the transmitting and receiving devices (the BU7963GUW and
BU7964GUW, respectively). Table 6 shows the PCLK input frequency ranges and transmission data rate ranges for the
LS pin settings.

MSDL3 Pin Assignment
RVS determines the assignment of MSDL3 pins, CLK+ / CLKâ, D0+ / D0â, D1+ / D1â and D2+ / D2-. Only the
MSDL3 high-speed signaling pins are affected by RVS, while pin assignment of other functions does not change.
User can select the assignment from âstraightâ (default) and âflippedâ assignment in order to minimize channel-to-channel
skew in PWB design. Table 7 shows the MSDL3 pin assignment, and Fig.5 shows the âstraightâ and âflippedâ
