standard PAL.
Setting AD_PAL_EN to 1 enables the detection of standard PAL.
SFL_INV, Subcarrier Frequency Lock Inversion
This bit controls the behavior of the PAL switch bit in the SFL
(Genlock Telegram) data stream. It was implemented to solve
some compatibility issues with video encoders. It solves two
problems.
First, the PAL switch bit is only meaningful in PAL. Some
encoders (including Analog Devices encoders) also look at the
state of this bit in NTSC.
Second, there was a design change in Analog Devices encoders
from ADV717x to ADV719x. The older versions used the SFL
(Genlock Telegram) bit directly, whereas the later ones invert
the bit prior to using it. The reason for this is that the inversion
compensated for the one-line delay of an SFL (Genlock
Telegram) transmission.
As a result, ADV717x encoders need the PAL switch bit in the
SFL (GenLock Telegram) to be 1 for NTSC to work. Also,
ADV7190/ADV7191/ADV7194 encoders need the PAL switch
bit in the SFL to be 0 to work in NTSC. If the state of the PAL
switch bit is wrong, a 180° phase shift occurs.
In a decoder/encoder back-to-back system in which SFL is used,
this bit must be set up properly for the specific encoder used.
SFL_INV, Subcarrier Frequency Lock Inversion,
Address 0x41 [6]
Setting SFL_INV to 0 (default) makes the part SFL-compatible
with ADV7190/ADV7191/ADV7194 encoders.
Setting SFL_INV to 1 makes the part SFL-compatible with
ADV717x and ADV7173x encoders.
Lock Related Controls
Lock information is presented to the user through Bits[1:0] of
the Status Register 1. See the STATUS_1[7:0], Address 0x10 [7:0]
section. Figure 16 outlines the signal flow and the controls
available to influence the way the lock status information is
generated.
