EL4585C Datasheet PDF - Elantec -> Intersil

General Description
The EL4585C is a PLL (Phase Lock Loop) sub system, designed for video applications, but also suitable for general purpose use up to 36 MHz. In a video application 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.

FEATUREs
• 36 MHz, general purpose PLL
• 8 FSC timing. (Use the EL4584 for 4 FSC)
• Compatible with EL4583C Sync Separator
• VCXO, Xtal, or LC tank oscillator
• k2nS jitter (VCXO)
• User-controlled PLL capture and lock
• Compatible with NTSC and PAL TV formats
• 8 pre-programmed popular TV scan rate clock divisors
• Single 5V, low current operation

APPLICATIONs
• Pixel Clock regeneration
• Video compression engine (MPEG) clock generator
• Video Capture or digitization
• PIP (Picture In Picture) timing generator
• Text or Graphics overlay timing
