Clock Input for DSPLLq.
Differential input clock. This input can also be driven with a
single-ended signal. Input frequency range is 2 kHz to 710 MHz.

DSPLLq Loss of Lock Indicator.
These pins function 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_PINn = 0, this pin will tri-state. Active polarity is
controlled by the LOL_POLn bit. The PLL lock status will always
be reflected in the LOL_INT read only register bit.

ILVCMOS DSPLLq Input Clock Select/Active Clock Indicator.
Input: This pin functions as the input clock selector between
CKIN and OSC.
0 = Select CKIN1.
1 = Select OSC (Internal).
Must be high or low. Do not float. If a DSPLL is not used, its
CS_CA_q pin should be tied high.
