TOSHIBA BiCMOS Integrated Circuit Silicon Monolithic
TB1328FG
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.
www.DataSheet4U.com The TB1328FG is equipped with an I2CBUS interface through
which various functions can be controlled.
