description
The THS8134 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 THS8134
has a sampling rate up to 80 MSPS. The device consists of three 8-bit D/A converters and additional circuitry
for bi-level/tri-level sync and blanking level generation in video applications.
THS8134 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 is generated in a 7:3 ratio, compliant with SMPTE standards for GBR and
YPbPr signals.
Furthermore, the THS8134 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.
The position of this defined (blanking) level and the temperature range, over which the maximum imbalance
between the inserted analog syncs (KIMBAL(SYNC)), are the only differences between the unrev, revA, and revB
device versions. Refer to the Available Options table.
