COLOR TV/VTR PLL IF SIGNAL PROCESSING IC
The μPC1820 is a semiconductor integrated circuit for processing the color TV/VTR PIF/SIF signals. This IC is housed in a 30-pin shrink dual-in-line package (DIP). Its main feature are supported by the built-in keyed-pulse generator needed for the L-SECAM, the VTR-oriented EQ amplifier, the SECAM-L/PAL B/G switch, the PLL VCO circuit, and the split sound carrier output.
