DESIGN FEATURES
OUTPUT OVERSAMPLING
The ADV7342/ADV7343 include two on-chip phase-locked
loops (PLLs) that allow for oversampling of SD, ED, and HD
video data. Table 41 shows the various oversampling rates
supported in the ADV7342/ADV7343.
SD Only, ED Only, and HD Only Modes
PLL 1 is used in SD only, ED only, and HD only modes. PLL 2 is
unused in these modes. PLL 1 is disabled by default and can be
enabled using Subaddress 0x00, Bit 1 = 0.
External Sync Polarity
For SD and ED/HD modes, the ADV7342/ADV7343 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 polarity other than the default is needed 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.
SD and ED/HD Simultaneous Modes
Both PLL 1 and PLL 2 are used in simultaneous modes. The use
of two PLLs allows for independent oversampling of SD and
ED/HD video. PLL 1 is used to oversample SD video data, and
PLL 2 is used to oversample ED/HD video data. In simultaneous
modes, PLL 2 is always enabled. PLL 1 is disabled by default and
can be enabled using Subaddress 0x00, Bit 1 = 0.
