Clock A
CLKA: This clock input is a DS3 signal(44.736MHz +/-20ppm) when the CLAD is disabled or it
is one of the CLAD reference clock signals when the CLAD is enabled.
Clock B
CLKB: This pin is a E3(34.368 MHz +/-20 ppm) input signal when the CLAD is disabled or it
can be enabled to output a generated clock when the CLAD is enabled. The pin is driven low
when it is not selected to output a clock signal and the CLAD is enabled. Refer to
Clock C
CLKC: This pin is a STS-1 (51.84 MHz +/-20ppm) input signal when the CLAD is disabled or it
can be enabled to output a generated clock when the CLAD is enabled. The pin is driven low
when it is not selected to output a clock signal and the CLAD is enabled. Refer to
