Functional Description

3.12
T0 / T4 APLL
A T0 APLL and a T4 APLL are provided for a better jitter and wander
performance of the device output clocks.
The bandwidths of the T0/T4 APLL are set by the T0_APLL_BW[1:0]
/ T4_APLL_BW[1:0] bits respectively. The lower the bandwidth is, the
better the jitter and wander performance of the T0/T4 APLL output are.
The input of the T0/T4 APLL can be derived from one of the T0 DPLL
outputs, as selected by the T0_APLL_PATH[3:0] / T4_APLL_PATH[3:0]
bits respectively.
Both the APLL and DPLL outputs are provided for selection for the
device output.
3.13
OUTPUT CLOCKS & FRAME SYNC SIGNALS
The device supports 2 output clocks and 1 frame sync output signal
altogether.
3.13.1
OUTPUT CLOCKS
The device provides 2 output clocks.
OUT1 outputs a PECL or LVDS signal, as selected by the
OUT1_PECL_LVDS bit. OUT2 outputs a CMOS signal.
The outputs on OUT1 and OUT2 are variable, depending on the sig-
nals derived from the T0 DPLL and T0/T4 APLL outputs, and the corre-
sponding OUTn_PATH_SEL[3:0] bits (n = 1 or 2). The derived signal can
be from the T0 DPLL and T0/T4 APLL outputs, as selected by the corre-
sponding OUTn_PATH_SEL[3:0] bits (n = 1 or 2). If the signal is derived
from one of the T0 DPLL outputs, please refer to Table 22 for the output
frequency. If the signal is derived from the T0/T4 APLL output, please
refer to Table 23 for the output frequency.
The outputs on OUT1 and OUT2 can be inverted, as determined by
the corresponding OUTn_INV bit (n = 1 or 2).
Both the output clocks derived from T0 selected input clock are
aligned with the T0 selected input clock every 125 s period.
