ADV7300A/ADV7301A
HD 4:2:2 to 4:4:4 Interpolation Filters and Chroma SSAF
It is recommended to input data in 4:2:2 Input Mode to make
use of the HD chroma SSAFs on the ADV7300A/ADV7301A.
This filter has a 0 dB pass-band response and prevents signal
components from being folded back into the frequency band. In
4:4:4 Input Mode, the video data is already interpolated by the
external input device and the chroma SSAFs of the ADV7300A/
ADV7301A are bypassed.
The chroma SSAF is controlled with Address 13h, Bit 5.
When the HD input format is 4:2:2, the HD Chroma Input Bit
[Address 13h, Bit 6] must be set to
“
1.
”
2 /4 /8 Oversampling Filters
The oversampling filters are enabled in setting the PLL ON
control [Subaddress 00h, Bit 1] to
“
1.
”
If enabled, PS and
ITU-R.BT656 data is output at a rate of 108 MHz, HDTV at a
rate of 148 MHz.
