LC89978M

Ordering number : EN5546A CMOS LSI LC89978M CCD Delay Line for Multi-System Overview The LC89978M is a CCD delay line for multi television system that incorporates a comb filter to remove noise from the chrominance signal and a 1-H delay line for the luminance signal. Package Dimensions unit: mm 3111-MFP14S [LC89978M] Features 5-V single-voltage power supply Built-in 4 × PLL frequency multiplier circuit allows 4fsc operation from an fsc (3.58 MHz) input. Can be switched between the NTSC/M, PAL/GBI, and PAL/M formats by setting control pin values. Includes a built-in crosstalk exclusion comb filter for the chrominance signal that provides high-precision comb characteristics in an adjustment-free circuit. Peripheral circuits provided on chip for operation with a minimum of external components. Positive-phase signal input, positive-phase signal output (luminance signal) SANYO: MFP14S Functions CCD shift registers (for chrominance and luminance signals) Timing generator and clock driver for CCD Delay time selective circuit CCD signal adder Auto-bias circuit Sync tip clamp circuit (luminance signal) Center bias circuit (chrominance signal) Sample-and-hold circuit 4 × PLL frequency multiplier circuit 4fsc clock output circuit High voltage generator for CCD Reset Drain (RD).
