CCD Delay Line Series
MN3883S
Full Multi-PAL-Compatible CCD Video Signal Delay Element
Overview
The MN3883S is a CCD signal delay element for video
signal processing applications.
It contains such components as a shift register clock driver, charge I/O blocks, 1/2nd frequency doubler, two switchable CCD analog shift registers, a clamp bias cir­cuit, resampling output amplifiers, a mode selection cir­cuit and booster circuits.
When the switch input is "H" level, the MN3883S samples the input using the supplied clock signal with a frequency 7.15909 MHz of twice the NTSC color signal subcarrier frequency, and after adding in the attached fil­ter delay, produces independent delays of 1 H (the hori­zontal scan period for the NTSC system) each for the two lines.
When the switch input is "M" level, the MN3883S samples the input using the supplied clock signal with a frequency 8.8672375 MHz of twice the PAL color signal subcarrier frequency, and after adding in the attached fil­ter delay, produces independent delays of 1 H (the hori­zontal scan period for the NTSC system) each for the two lines.
When the switch input is "L" level, the MN3883S samples the input using the supplied clock signal with a frequency 8.8672375 MHz of twice the PAL color signal subcarrier frequency, and after adding in the attached fil­ter delay, produces independent delays of 1 H (the hori­zontal scan period for the PAL system) for the Y output and 2 H for the C output.
