Figure 9. Simplified Schematic of the LVDS Input
S0389-01
Figure 10 shows the typical input connections. The transmission line lengths must be matched from the driver to
the THS788 input [<0.5 inch (1.27 cm) difference] and terminated in a 100-Ω resistor placed close [<0.25 inch
(0.635 cm)] to the TMU input pins. The resistor total tolerance should be below 5%. The power dissipation is
below 5 mW, so small surface-mounted resistors are preferred.
