ICLK output and back-end clock is line-locked clock LLC from decoder
ICLK output and back-end clock is XCLK from X port
ICLK output is LLC and back-end clock is LLC2 clock
Back-end clock is the ICLK input
IDQ pin carries the data qualifier
IDQ pin carries a gated back-end clock (DQ AND CLK)
IDQ generation only for valid data
IDQ qualifies valid data inside the scaling region and all data outside the
scaling region

XRDY output signal is A/B task flag from event handler (A = 1)
XRDY output signal is ready signal from scaler path (XRDY = 1 means
the SAF7118 is ready to receive data)
