Centuerty4US.ceomm iconductor Inc. TV ECnSc8o5d5e2rGENERAL DESCRIPTION
eCS8552 provides full conversion from digital video
hformat YCbCr into NTSC/PAL composite and S-
taSvideo. It can be used in VCD, DVD, digital VCR
application.
aTwo-times oversampling reduces the output filter
.Drequirements and guarantees no alias interference
wby internal UV filters and Y filter.
wTwo 9-bit DACs provides two channels for a S-
w video output port or two composite video outputs with
FEATURES
• Designed special for VCD, Karaoke, digital VCR,
DVD, DIGITAL set-top box.
• Support 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
• Support CCIR-6-1 for mat, non-square pixel
high quality of image.
32-pin package and pin assignment make CS8552
U.comcompatible with major vendors.
• 2x oversampling simplify external filtering
• 6MHz and 1.3MHz anti-alias filters for Y and U/V
channels each
• On-chip color bar generation
• 2 channels of 9-bit DAC
• Support master and slave modes
• Support 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; other PAL formats have setup disabled with
normal 100% scaling. 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 enabled with amplified 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.

ANTI-ALIAS FILTERS CHARACTERIS
The Y and the U, V are up-samples to clk, 27MHz after 4:2:2 to 4:4:4 conversion. Y is filtered by a filter whose
passband is 6MHz. And U, V are also filtered by passband = 1.3MHz filters.
