GENERAL DESCRIPTION
The SPT2210 is a single-chip video encoder that is ca-
pable of converting digital video data (YCrCb) into analog
NTSC or PAL video signals. Two digital input formats are
supported: 4:2:2 (YCrCb) and 4:1:1 (YCrCb). It internally
generates the proper SYNC and color burst signals for
NTSC (525 lines/60 Hz) and PAL (625/50 Hz) video stan-
dards operating in any one of three sample rate modes:
CCIR 601, square pixel and 4Fsc.
Composite or Y/C S-Video analog video output is gener-
ated via two 8-bit internal video DACs. In addition, the
APPLICATIONS
• Video cameras
• Digital video tape recorders
• Video conference equipment
• Video frame grabbers
• Set-top boxes
• Video projection and displays
• Video printers
• Video game machines
• Multimedia PCs
SPT2210 supports external or chroma key functions for
color graphics pixel-by-pixel overlay. It has a 16-color
lookup-table overlay palette which is fully programmable.
It also has an on-chip vertical interpolation filter that can
be activated to reduce jaggy noise and flicker. The chip
also features an internal test color bar pattern generator.
The SPT2210 operates from a single +3.3 V supply and
is built in a 0.5 µm CMOS process. It is available in a 64-
lead PQFP package and operates over the commercial
temperature range.
