eet4U.com TV Encoder CS8552GENERAL DESCRIPTION
hThe CS8552 provides full conversion from digital
Svideo format YCbCr into NTSC/PAL composite and
taS-video. It can be used in VCD, DVD, and digital
aVCR applications.
.DTwo times oversampling reduces the output filter
wrequirements and guarantees no alias interference
wby internal UV filters and Y filter.
w Two 9-bit DACs provide two channels for a S-
FEATURES
• Especially designed for VCD, Karaoke, digital
VCR, DVD, DIGITAL set-top box.
• Supports the following 4 modes:
NTSC, PAL-M, PAL-BDGHI, PAL-Nc.
• 8-bit 4:2:2 YCbCr inputs for glueless interface to
MPEG decoders.
• CVBS (composite YC) or S-video (Y and C)
outputs.
video output port or two composite video outputs with
high quality image.
32-pin package and pin assignment make the
U.comCS8552 compatible with major vendors.
• Supports CCIR-601 format, non-square pixel
• 2x oversampling simplifying external filtering.
• 6MHz and 1.3MHz anti-alias filters for Y and U/V
channels each.
• 2 channels of 9-bit DAC.
• Supports master and slave modes.
• Supports interlace operation only.
• Automatic mode detection/switching in slave
mode.
• 3.3V supply voltage; 5V tolerant for all digital I/O
pins.

EFIELD is used when configured as a master. When EFIELD is set low, the Normal vsync* signal is
output on the VSYNC* pin. When EFIELD is set high, field ID information is output on the VSYNC*
pin (VSYNC* low for Field-1 and high for Field-2)
PAL625 is used when configured as a master. When PAL625 is set low, 525-line operation is
selected. When PAL625 is set high, 625-line operation is selected. This mode is set by automatic
detection when configured as a slave.
YCSWAP should normally be set to zero. When configured as a slave, this bit can be set high to
swap the luma and chroma samples, thus altering the pixel sequence with respect to the incoming
HSYNC* timing reference.
SETUP is normally low for the common video modes. The setup and scaling function is toggled
when this bit is high. When SETUP is low, the 7.5IRE setup is enabled for NTSC and PAL-M with
scaling amplified for a 92.5% black-to-white range. When SETUP is high, the 7.5 IRE setup is
disabled for NTSC and PAL-M with 100% black-to-white range scaling. Other PAL formats have
setup disabled with normal 100% scaling.
PALSA is normally low for the common video modes. South American video Standards can be
enabled by setting this bit high. For 525-line operation, the PALSA enables PAL-M for Brazil; in 625-
line operation, the PALSA enables PAL-Nc for Argentina.
