7. Application Notes
7.1. Differences between VPX 322xE
and VPX 322xD-C3
The following items indicate the differences between the
VPX 322xE and the VPX 322xD:
Internal
– The VPX 3226E includes a high-performance adap-
tive 4H combfilter Y/C separator with adjustable verti-
cal peaking
– The center frequency for horizontal peaking is select-
able in 3 steps (low, middle, high)
– The task flag of the ITU-R656 headers can be used to
distinguish between VBI and video data.
– Macrovision detection
– new LLC timing (optional)
– optional gating of LLC to assure a fixed number of
clock cycles per line.
– clock-synchronized bus arbitration via OE (optional)
External
– 3.3 V digital supply voltage
7.2. Differences between VPX 322xE and VPX 3220A
The following items indicate the differences between the
VPX 322xE and the VPX 3220A:
Internal
– The control registers (I
2
C and FP-RAM) contain signif-
icant changes.
– VPX 3225E and VPX 3226E incorporate a text slicer.
– Raw ADC data is supported (sampling frequency of
20.25 MHz/8 bit, output data rate 13.5 MHz/16 bit or
27 MHz/8 bit).
– VPX 322xE does not support RGB and compressed
video data output formats. The VPX 322xE supports
ITU-R601 and ITU-R656.
– The VPX 322xE does not provide an asynchronous
output mode, PIXCLK functions as an output only. The
VPX 322xE supports half-clock data rate (6.75 MHz).
– The VPX 322xE does not provide a video data rate of
20.25 MHz at the output interface.
– The VPX 322xE supports low power mode.

FIELD
– The VPX 322xE does not use the internal I
2
C bus for
power-up initialization. Resultingly, the I
2
C interface
will not be locked during that period.
– The VPX 322xE supports an 8-bit input or program-
mable output port B[7:0] if the device uses only port
A[7:0] for video data output.
– The VPX 322xE provides a HREF signal with a fixed
low period, whereas the width of the high period will
vary while the video input signal varies.
