TB1311AFG
Audio SW, Video SW, Sync Separation and H/V Frequency Counter IC for TVs
The TB1311AFG includes audio and video SW blocks, prefilters
for A/D converters, sync separators, and an H/V format detector for
TV signals.
The TB1311AFG contributes to a reduction in the proportion of the
PCB occupied by LCR filters and to the simplification of designs on
analog interfaces.
The TB1311AFG has an I
2CBUS interface through which various
functions can be controlled.
