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.
