Overview

The LC89962 and LC89962M are delay line circuits that provide a delayed signal by a 1H period of NTSC format with an external low-pass filter.

Features

• Requires only the input of a 3.58-MHz clock to produce a 1H delayed signal and the external low-pass filter.

• Uses a 5-V single-voltage power supply.

• Requires a minimal number of external components due to the peripheral components provided on chip.

• Output signal has the same phase as the input signal.

• Operation has a 4fsc clock synchronized with the input clock allows these products to be used as wide bandwidth delay lines.

• A 4fsc clock can be output from the 4FSC pin (pin 7).

Functions

• 906-bit CCD shift register

• Timing generator and CCD driver circuits

• Auto-bias circuit

• Sync-tip clamp circuit

• Sample-and-hold and output amplifier circuits

• 4 × PLL circuit

• 4fsc output circuit
