Analog Reconstruction Filter for HDTV Using the

THS8133, THS8134, THS8135, THS8200

Karl Renner

Digital Audio Video Department

ABSTRACT

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 up 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.

Introduction

The THS8133, THS8134, THS8135, and THS8200 comprise a family of graphics/video chips

that have triple digital-to-analog converters (DACs) that convert digital graphics signals

GBR/YPbPr to analog. They insert bilevel or trilevel syncs into the green/luma signal. The trilevel

sync is used for horizontal synchronization of high definition (HD) television signals. Table 1 lists

the chips and their capabilities. The THS8200 incorporates a 1:2 upsampling and interpolation

filter, which results in a simplification of the filter design that is used to reconstruct the analog

output signal. The advantages of 2x oversampling are examined for the high definition (HD)

television application.

Table 2 lists the different HD standards. The 1080i format corresponds to system 4 in Table 2

and the 720p format corresponds to system 1 in Table 3. Both have a sampling rate of

74.25 MHz and a 30-MHz bandwidth requirement for the luma and RGB output filter.
