and one line. The default horizontal border size is four

Whentheinput signals forthemainand/or subchannel
are non-interlaced, joint line errors can occur. When
non-interlaced signals are input, the SAB9081
switches automatically to the non-interlaced mode.
When the prevent joint line error algorithm is switched
off (AlgOff is set to logic 1), joint line errors can still
occur in the 2-Field mode.
When a PAL signal is applied to the main channel and
an NTSC signal is applied to the subchannel, the
subchannel will automatically enter the 1-Field mode.
Now, a joint line error can occur. In the PAL/NTSC
mode, the subpicture will be smaller than the main
picture (difference of approximately 40 lines).
When an NTSC signal is applied to the main channel
and a PAL signal is applied to the subchannel, the
subchannel will automatically enter the 1-Field mode.
Now, a joint line error can occur. In the NTSC/PAL
mode, the subpicture will be larger than the main
picture (difference of approximately 40 lines).

Acquisition channel ADCs and clamping
The analog input signals are converted to digital signals by
three ADCs per channel. The resolution of the ADCs is
8 bits (DNL is 7 bits and INL is 6 bits) and the sampling is
performed at the system clock frequency of 28 MHz for the
Y input. A bias voltage (V
bias
) is used to decouple the AC
components on internal references.
The inputs should be AC coupled and an internal clamp
circuit (using external clamp capacitors) will clamp the
input to a level derived internally from V
ref(B)(MA/SA)
for the
luminance channels and, forthe chrominance channels, to

starts at the active edge of the burst key. Internal video

, from the HSYNC, which is approximately
28 MHz.
DACs and video buffers
The 28 MHz digital video signals are fed to the 8-bit DACs
that produce the required analog video signals. The video
buffers amplify these signals prior to being fed to the
output to drive another device.
