TB1311AFG

TB1311AFG TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic 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 www.DataSheet4U.com analog interfaces. 2 The TB1311AFG has an I CBUS interface through which various functions can be controlled.
