SYNC Processor, Frequency Counter IC for TV Component Signals

TA1318NG is a sync processor for TV component signals.

TA1318NG provides sync and frequency counter processing for external input signals.

These functions are integrated in a 24 pin dual-in-line shrink-type plastic package.

TA1318NG provides I2C bus interface, so various functions and controls are adjustable via the bus.

Features

• Vertical synchronization circuit (525I, 525P, 625I, 750P, 1125I, 1125P, PAL 100 Hz, NTSC 120 Hz)

• Horizontal and vertical frequency counter

• Horizontal PLL

• Accepts 2-level and 3-level sync

• Accepts both negative and positive HD and VD

• Clamp pulse output

• HD, VD output (polarity inverter)

• Separated sync output

• Mask for the copy guard signal
