DETAILED FUNCTIONALITY
ANALOG FRONT END
The analog front-end section contains four high quality 10-bit
ADCs, and the six analog input channel mux enables multisource
connection without the requirement of an external mux. It also
contains
•
•
•
SDP PIXEL DATA OUTPUT MODES
The SDP pixel data output modes are the following:
•
•
CP PIXEL DATA OUTPUT MODES
CP pixel data output modes include single data rate (SDR) and
double data rate (DDR) as follows:
•
•
•
•
Four current and voltage clamp control loops to ensure
that any dc offsets are removed from the video signal
SCART functionality and SD RGB overlay on CVBS that
are controlled by fast blank input
Four internal antialias filters to remove out-of-band noise
on standard definition input video signals
8-/10-bit ITU-R BT.656 4:2:2 YCrCb with embedded time
codes and/or HS, VS, and FIELD
16-/20-bit YCrCb with embedded time codes and/or HS,
VS, and FIELD
SDR 8-/10-bit 4:2:2 YCrCb for 525i, 625i
SDR 16-/20-bit 4:2:2 YCrCb for all standards
DDR 8-/10-bit 4:2:2 YCrCb for all standards
DDR 12-bit 4:4:4 RGB for graphics inputs

COMPOSITE AND S-VIDEO PROCESSING
Composite and S-Video processing features offer support for
NTSC M/J, NTSC 4.43, PAL B/D/I/G/H, PAL60, PAL M, PAL N,
and SECAM (B, D, G, K, and L) standards in the form of CVBS
and S-Video as well as super-adaptive, 2D, 5-line comb filters
for NTSC and PAL give superior chrominance and luminance
separation for composite video. They also include full automatic
detection and autoswitching of all worldwide standards (PAL,
NTSC, and SECAM) and automatic gain control with white
peak mode to ensure the video is always processed without loss
of the video processing range. Other features are
