● Automatic Forced Asynchronous Mode to Remove Jitter
● Improved Low Voltage Start–Up Operation
● Lower Zero–State Horizontal–Drive Pulse Output
● Improved Symmetry for Horizontal–Drive Output
● Improved Automatic Standard Operation
● Noise Detector
● Handles Standard NTSC and Non–Standard Signals
● Automatic Mode Recognition
● Clock Input
● Vertical Ramp (Sawtooth) Generator
● Vertical Amplifier
● Vertical Blanking Generator
Horizontal Drive Pulse Output
● Ratio–Voltage Regulator
● Inherent Interlace for NTSC Signals
● Vertical–Hold Control Eliminated
● Supply Voltage Range: 10.8V to 13.2V
● Rapid Pull–In
● Co–Channel Sync Lockout for NTSC Signals
● I2L Logic
