TOSHIBA BiCMOS Integrated Circuit Silicon Monolithic
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. 2 www.DataSheet4U.com The TB1328FG is equipped with an I CBUS interface through which various functions can be controlled. LQFP64-P-1010-0.50A Weight: 0.34 g (typ.)
