EL4585 is a PLL (lock -in -loop) subsystem, specially video video Application and design are also applicable to universal use of up to 36MHz. In video applications, the device generates a TTL/CMOS compatible pixel clock (CLK-OUT), which is a multiples of the TV horizontal scanning rate and lock it.
The reference signal is a horizontal synchronous signal, and the TTL/CMOS format can easily export from an analog composite video signal with EL4583 synchronizer. Provide an input signal to Coast " to refer to the application of periodic interference in the reference video
