ADV7320/ADV7321
HD ASYNC TIMING MODE
[Subaddress 0x10, Bits 3 and 2]
Rev. 0 | Page 42 of 88
For any input data that does not conform to the standards
selectable in input mode, Subaddress 0x10, asynchronous
timing mode can be used to interface to the ADV7320/ADV7321.
Timing control signals for HSYNC, VSYNC, and BLANK must
be programmed by the user. Macrovision and programmable
oversampling rates are not available in async timing mode.
In async mode, the PLL must be turned off [Subaddress 0x00,
Bit 1 = 1]. Register 0x10 should be programmed to 0x01.
Figure 58 and Figure 59 show examples of how to program the
ADV7320/ADV7321 to accept a high definition standard other
than SMPTE 293M, SMPTE 274M, SMPTE 296M, or ITU-R
BT.1358.
Table 26 must be followed when programming the control signals
in async timing mode. For standards that do not require a trisync
level, P_BLANK must be tied low at all times.

When async timing mode is enabled, P_BLANK, Pin 25, becomes an active high input. P_BLANK is set to active low at Address 0x10, Bit 6.
