Pin Control Modes
For the following tables, Low is defined as installing a jumper between pins 5 and 6 on the
desired header. A HIGH is defined as installing a jumper between pins 1 and 2 on the desired
header.
If EN_PIN_CTRL = LOW (jumper installed between header positions 5 and 6) then the
following table describes possible output configurations:
Header Output Groups Header = Low Header = Middle Header = High
Type0 CLKout0 – CLKout3 LVDS Powerdown LVPECL
Type1 CLKout4 – CLKout7 LVDS LVCMOS (Norm/Inv) LVPECL
Type2 CLKout8 – CLKout13 LVDS LVCMOS (Norm/Inv) LVPECL
DivVal0 CLKout0-3 Divider ÷1 ÷4 ÷2
DivVal1 CLKout4-7 Divider ÷1 ÷4 ÷2
DivVal2 CLKout8-11 Divider ÷1 ÷4 ÷2
CLKout12-13 Divider ÷8 ÷512 ÷16
