TC90A67F
Single Chip Picture-in-Picture IC (PAL/NTSC)
TC90A67F is a Picture-in-Picture (PIP) IC including a PIP
controller and a PAL/NTSC decoder function on a chip.
TC90A67F has an ADC, a video decoder, a vertical filter, a field
memory, DACs and so on, so that it is easy to design a PIP
application with the least external components.
