CLKINT and FBOUT skew channel, or from –1.1ns to

+3.5ns if additional DDR skew channels are enabled.

Four independent programmable DDR skew chan-

nels from –0.3ns to +0.4ns with step size ±100ps.

Support 2-wire I2C serial bus interface.

The PLL102-108 is a zero delay buffer that distributes

a single-ended clock input to ten pairs of differential

clock outputs and one feedback clock output. Output

signal duty cycles are adjusted to 50%, independent of

the duty cycle at CLK_INT. The PLL can be bypassed

for test purposes by strapping AV_ddto ground.
