description
The TMS320AV410/411 digital NTSC/PAL encoder converts digital RGB and YCbCr signals to conform to the
NTSC/PAL standard. Signals may be output in Y, C, composite, and RGB formats. The integrated
synchronization signal generator and three-channel D/A converter minimize the requirement for additional
external logic. An internal matrix circuit performs YCbCr to RGB conversion. The ’AV410/411 is designed for
MPEG video applications such as digital video disk, video CD, CATV set-top box, and PC applications. Host
control of the ’AV410/411 is achieved via an I
2
C compatible interface or a general purpose four-line host
interface. A simplified stand-alone mode allows the ’AV410/411 to operate without a host controller. The device
uses a dual supply configuration for reduced power dissipation. The core circuitry operates at 3.3-V while the
device input/output operates at 5-V to provide a TTL-compatible interface.
The TMS320AV410 has the capability to apply Macrovision (version 7.0) to the video output signals.
Macrovision is an anticopy protection that allows an audience to view, but not record, the video signal from a
videocassette recorder. In order to obtain this device and the associated Macrovision programming information,
the customer must provide proof of Macrovision licensing. Please contact your nearest Texas Instruments (TI
)
sales representative for more information.
The TMS320AV411 is identical in functionality to the TMS320AV410 without the Macrovision function.
The TMS320AV410 and the TMS320AV411 are characterized for operation from –10
°
C to 70
°
C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
