TA1318AFG
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA1318AFG
SYNC Processor, Frequency Counter IC for TV Component Signals
TA1318AFG is a sync processor for TV component signals.
TA1318AFG provides sync and frequency counter processing
for external input signals.
These functions are integrated in a 30 pin SSOP-type plastic
package.
TA1318AFG provides I
2
C bus interface, so various functions
and controls are adjustable via the bus.
