EL4584CSZ-T7

水平同步锁相，为4fsc Horizontal Genlock, 4FSC

The EL4584 is a PLL Phase Lock Loop sub system, designed for video applications but also suitable for general purpose use up to 36MHz. In video applications, this device generates a TTL/CMOS compatible Pixel Clock CLK OUT which is a multiple of the TV horizontal scan rate and phase locked to it.
