Description
VOD Level Select
VODSEL = L; LVDS Driver Output is ≈±400 mV (R_L = 100Ω)
VODSEL = H; LVDS Driver Output is ≈±750 mV (R_L = 100Ω)
For normal applications, set this pin LOW. For long cable applications where a larger VOD is
required, set this pin HIGH.
RESERVED – This pin MUST be tied LOW.

Transmitter LVDS True (+) Output. This output is intended to be loaded with a 100Ω load to the
DOUT+ pin. The interconnect should be AC Coupled to this pin with a 100 nF capacitor.
Transmitter LVDS Inverted (-) Output This output is intended to be loaded with a 100Ω load to the
DOUT- pin. The interconnect should be AC Coupled to this pin with a 100 nF capacitor.
