LC89975M
PAL-Format Delay Line
Preliminary
Overview
The LC89975M is a lower-cost PAL-Format CCD delay
line based on the LC89970M, with the sizes of chip and
package miniaturized and the external parts count reduced.
Features
• 5 V single-voltage power supply
• On-chip 3× PLL circuit for 3·fsc operation from an fsc
(4.43 MHz) input
• Supports PAL/GBI and 4.43 NTSC systems, selected by
a control pin input
• Includes an on-chip comb filter for chrominance signal
crosstalk exclusion. This adjustment-free circuit
provides high-precision comb characteristics.
• Peripheral circuits included on chip to allow operation
with minimal external circuits.
• Positive-phase signal input, positive phase signal output
(luminance signal)
