LOL
O
LVCMOS
PLL Loss of Lock Indicator.
This pin functions as the active high PLL loss of lock indicator if the
LOL_PIN register bit is set to 1.
0 = PLL locked
1 = PLL unlocked
If LOL_PIN = 0, this pin will tristate. Active polarity is controlled by
the LOL_POL bit. The PLL lock status will always be reflected in the
LOL_INT
read only register bit.

DEC
I
LVCMOS
Skew Decrement.
A pulse on this pin decreases the input to output device skew by
1/fOSC (approximately 200 ps). There is no limit on the range of
skew adjustment by this method.
Pin control is enabled by setting INCDEC_PIN =1. If
INCDEC_PIN
= 0, this pin is ignored and output skew is controlled
via the CLAT register.
If both INC and DEC are tied high, phase buildout is disabled and
the device maintains a fixed-phase relationship between the
selected input clock and the output clock during an input clock
switch.
See the Si53xx Family Reference Manual for more details.
This pin has a weak pull-down.

INC
I
LVCMOS
Skew Increment.
A pulse on this pin increases the input to output device skew by
1/fOSC (approximately 200 ps). There is no limit on the range of
skew adjustment by this method.
Pin control is enabled by setting INCDEC_PIN =1. If
INCDEC_PIN
= 0, this pin is ignored and output skew is controlled
via the CLAT register.
If both INC and DEC are tied high, phase buildout is disabled and
the device maintains a fixed-phase relationship between the
selected input clock and the output clock during an input clock
switch.
See the Si53xx Family Reference Manual for more details.
Note:
INC does not increase skew if NI_HS = 4.
This pin has a weak pull-down.
