Datasheet Summary
Ordering number : EN- 4872A
CMOS IC
LC74401E, 74402, 74402E
PIP Controllers
Overview
The LC74401E, LC74402, and LC74402E are memory controllers for TV set and VCR PIP (picture in picture) systems. Since these LSIs include three D/A converter circuits, a ponent PIP system can be constructed by bining one of these LSIs with memory and an A/D converter such as the LC7480.
Features
- Horizontal resolution: 600 TV lines- 1
- Three D/A converters (for the Y, R-Y, and B-Y signals) are incorporated in the PIP memory controller block.
- High image quality is supported by vertical filter function frame memory processing- 2.
- I2C bus controlled.
- Built-in PLL circuit (requires an external LPF)
