Fully programmable static gain or Automatic Gain
Control (AGC) for the selected CVBS or Y/C channel
Switchable white peak control
Two built-in analog anti-aliasing filters
Two 9-bit video CMOS Analog-To-Digital Converters
(ADCs), digitized CVBS or Y/C signals are available on
the IPD (Image Port Data) port under I
On-chip clock generator
Line-locked system clock frequencies
Digital PLL for horizontal sync processing and clock
generation, horizontal and vertical sync detection
Requires only one crystal (either 24.576 MHz or
32.11 MHz) for all standards
Automatic detection of 50 and 60 Hz field frequency,
and automatic switching between PAL and NTSC
standards

Enhanced ITU 656 output format on IPD output bus
containing:
– active video
– raw CVBS data for INTERCAST applications
– decoded VBI data
Detection of copy protected input signals according to
the macrovision standard. Can be used to prevent
unauthorized recording of pay-TV or video tape signals.
Both up and downscaling
Conversion to square pixel format
NTSC to 288 lines (video phone)
Phase accuracy better than

Independent scaling definitions for odd and even fields
Anti-alias filter for horizontal scaling
Provides output as
– scaled active video
