description
The THS8133 is a general-purpose triple high-speed D/A converter (DAC) optimized for use in video/graphics
applications. The device operates from a 5-V analog supply and a 3-V to 5-V range digital supply. The THS8133
has a sampling rate up to 80 MSPS. The device consists of three 10-bit D/A converters and additional circuitry
for bi-level/tri-level sync and blanking level generation in video applications.
THS8133 is also well suited in applications where multiple well-matched and synchronously operating DACs
are needed; for example, I-Q modulation and direct-digital synthesis in communications equipment.
The current-steering DACs can be directly terminated in resistive loads to produce voltage outputs. The device
provides a flexible configuration of maximum output current drive. Its output drivers are specifically designed
to produce standard video output levels when directly connected to a single-ended doubly-terminated 75
coaxial cable. Full-scale video/sync are generated in a 7:3 ratio, compliant with SMPTE standards for GBR and
YPbPr signals.
Furthermore, the THS8133 can generate both a traditional bi-level sync or a tri-level sync signal, as per the
SMPTE standards, via a digital control interface. The sync signal is inserted on one of the analog output
channels (sync-on-green/luminance) or on all output channels. Also, a blanking control signal sets the outputs
to defined levels during the nonactive video window.
Finally the input format can be either 3

10 bit 4:2:2. This enables a direct
interface to a wide range of video DSP/ASICs including parts generating ITU-BT.656 formatted output data.
