The THS8133, THS8134, THS8135, and the THS8200 devices are part of a family of chips for graphics and video applications, which contain triple DACs that operate from 80 MSPS to 240 MSPS. For television applications, an analog low-pass filter is required to reconstruct the signal that is input to the monitor. High definition television (HDTV) requires a sampling frequency of 74.25 MHz and has pass-band, transition band, and stop-band attenuation requirements, which affect the complexity of the filter. A higher sampling rate results in a lower filter complexity.
