NTE NTE1813 Datasheet

NTE1813

Integrated Circuit

Color Signal Processor for VCR

Description:

The NTE1813 is an integrated circuit in a 22–Lead DIP type package. When combined with the
NTE1814, this device provides the functions which process VCR color signals at the 2H/4H/6H mode
is NTSC systems.

Features:

D Low Operating Supply Voltage: VCC = 5V
D Low Power Consumption: 110mW
D AFC and APC System in Recording Mode. APC System Only During Playback Mode.
D Better S/N Ratio by Chroma ACC (2H/6H Mode).
