Description
Controls the output drive capability of the OUT1 driver.
0 = weak.
1 = strong (default).
Controls power-down functionality of the OUT1 driver.
0 = OUT1 active (default).
1 = OUT1 powered down.
OUT1 driver mode selection.
000 = CMOS, both pins active.
001 = CMOS, positive pin active, negative pin tristate.
010 = CMOS, positive pin tristate, negative pin active.
011 = CMOS, both pins tristate.
100 = LVDS.
101 = LVPECL (default).
110 = not used.
111 = not used.
Selects the polarity of the OUT1 pins in CMOS mode.
00 = positive pin logic is true = 1, false = 0/negative pin logic is true = 0, false = 1 (default).
01 = positive pin logic is true = 1, false = 0/negative pin logic is true = 1, false = 0.
10 = positive pin logic is true = 0, false = 1/negative pin logic is true = 0, false = 1.
11 = positive pin logic is true = 0, false = 1/negative pin logic is true = 1, false = 0.
These bits are ineffective unless Bits[5:3] select CMOS mode.
Controls OUT1 driver functionality.
0 = OUT1 is LVDS or LVPECL, per the OUTSEL pin (Pin 15) (default).
1 = OUT1 functionality defined by Bits[7:1].
Description
Unused.
Selects the signal source for OUT2.
0 = source for OUT2 is the output of the P
1 = source for OUT2 is the input reference (REF or XTAL).
Unused.
