TB1328FG
Audio SW, Video SW, Sync Separation and H/V Frequency Counter IC for TVs
The TB1328FG includes Audio and video SW blocks, pre-filters for
AD converter, sync separations and an H/V format detector for TV
signals.
The TB1328FG contributes to a reduction in the proportion of PCB
occupied by LCR filters and to the simplification of designs in analog
interfaces.
The TB1328FG is equipped with an I²CBUS interface through
which various functions can be controlled.
