Component SW, Sync Separation and H/V Frequency Counter IC for TVs
The TB1305FG and TB1308FG include a component SW block, a
prefilter for AD conversion, sync separation and H/V format
detectors for TV component video signals.
The TB1305FG and TB1308FG contribute to reduction in the
proportion of PCB occupied by LCR filters and to the simplification of
designs on analog interfaces.
The TB1305FG and TB1308FG are equipped with an I²CBUS
interface through which various functions can be controlled.
