CMOS, Color Processing Circuit for VCR

Description:

The NTE1814 is a CMOS LSI integrated circuit in an 18–Lead DIP type package designed for use

in VCR color signal processing circuits for VHS system video tape recorders. This device is used in

configuration with the NTE1813 for color signal processing in 2, 4, and 6Hr modes in NTSC VCR sys-

tems.

Features:

D In Recording, a Video Color Signal can be Converted into a Low–Frequency Video Color Signal

by AFC and REC APC.

D In Playback, the Low–Frequency Color Signal can be Converted into the Original Video Color

Signal on the Color Subcarrier Wave Frequency by PB APC and the Side Lock Detect Circuit.

D The NTE1814 Contains the Following Functions:

Rotary Circuit

DPLL (Digital Phase Locked Loop) Circuit

Side Lock Detect Circuit

Field Start Inhibit Pulse Generating Circuit

Burst Adjust Pulse Generating Circuit

Burst Gate Pulse Generating Circuit

Monostable Multivibrator Circuit

Phase Comparator

D Can be Miniaturized and Simplified with High Reliability

D Low Power Dissipation: 15mW @ 5V
