PAP/PIP/POP Controller for Wide-Screen TVs (PAL/NTSC)
TC90A66F
With built-in AD and DA converters (ADC/DAC), the TC90A66F is a picture-and-picture (PAP)/picture-in-picture
(PIP)/picture-out-picture (POP) controller IC for PAL and NTSC
formats. It is used in combination with field memory, video signal
processor ICs.
The TC90A66F enables a variety of picture display functions.
The IC is optimal to provide wide-screen TVs with additional
functionality.
