DESIGN FEATURES
OUTPUT OVERSAMPLING
The ADV739x includes an on-chip phase-locked loop (PLL)
that allows for oversampling of SD, ED, and HD video data. By
default, the PLL is disabled. The PLL can be enabled using
Subaddress 0x00, Bit 1 = 0.
Table 40 shows the various oversampling rates supported in the
ADV739x.
External Sync Polarity
For SD and ED/HD modes, the ADV739x parts typically expect
HS and VS to be low during their respective blanking periods.
However, when the CEA861 compliance bit is enabled (0x39,
Bit 5 for ED/HD modes and 0x86, Bit 3 for SD modes), the part
expects the HS or VS to be active low or high depending on the
input format selected (0x30, Bits[7:3]).
If a different polarity other than the default is required for
ED/HD modes, 0x3A, Bits[2:0] can be used to invert PHSYNCB,
PVSYNCB or PBLANKB individually regardless of whether
CEA-861-B mode is enabled. It is not possible to invert
S_HSYNC or S_VSYNC.
