Integrated Circuit
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
