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 I2CBUS interface through which various functions can be controlled.
