Description
The FS453 / FS454 is a video scan converter. It
can accept computer graphics, in many different
input resolutions and rates, and convert them to
broadcast quality video compliant with industry
standards as shown:
Format
NTSC (SD)
PAL (SD)
480p (HD)
720p (HD)
1080i (HD)
Standard
SMPTE-170M
ITU-R 624
EIA-770.2-A
SMPTE 296
SMPTE 274
HD inputs bypass the scaler and flicker filter,
and are formatted directly into HD compatible
Component (YPrPb) outputs.
The FS453 / FS454 can be used both as a TV
encoder and as a 75MHz DAC for VGA – XGA
outputs.
The digital video encoder generates Y/C, CVBS,
RGB and YPrPb output signals. These signals
can be combined to support RGB + CVBS for
SCART, YPrPb + CVBS or multiple CVBS and
Y/C DAC outputs.
The FS454 incorporates Macrovision 7 anti-copy
protection technology in the encoder, including
480p protection.
The programmable up and down scaler allows
the incoming resolution to be fitted to completely
mfill the output display screen. The
oprogrammable flicker filter is an advanced 2
.cdimensional filter that enhances text quality and
ueliminates artifacts. The degree of sharpness is
t4also programmable.
eThe digital progressive RGB inputs are scaled to
ethe ITU-R BT.601, 4:2:2 format. Vertical scaling
hand flicker filtering are done in the 4:2:2 format.
All parameters can be read and written via the
I2C compatible serial port. The flexibility of the
FS453 / FS454 allows a glueless digital
interface to most graphic display chips.
The FS453 / FS454 requires power from +1.8V
digital and +3.3V analog supplies. For external
components, it only needs a 27 MHz clock and
passive parts. The FS453 / FS454 is an 80-lead
Quad Flat Pack (PQFP) package.
