CLKOUT2 is a divided version of the reference frequency, f
and can be set to be a submultiple integer of f
where L = 0, 1, or 2). With L set to 0, the output of CLKOUT2 is
a delayed version of the signal appearing at OSCIN, exhibiting
the same duty cycle characteristics. With L set to 1 or 2, the
output of CLKOUT2 is a divided version of the OSCIN signal,
exhibiting a near 50% duty cycle, but without having a determi-
nistic phase relationship relative to CLKOUT1 (or RXCLK).
