ANALOG DEVICES RGB to NTSC/PAL Encoder AD722 handbook

Update: 30 September, 2023

The AD722 is a low cost RGB to NTSC/PAL Encoder that converts red, green and blue color component signals into their corresponding luminance (baseband amplitude) and chromi- nance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. These two outputs are also combined to provide composite video output. All three out- puts can simultaneously drive 75 Ω, reverse-terminated cables. All logical inputs are CMOS compatible. The chip operates from a single +5 V supply. No external delay lines or filters are required. The AD722 may be powered down when not in use. The AD722 accepts either FSC or 4FSC clock. When a clock is not available, a low cost parallel-resonant crystal (3.58 MHz (NTSC) or 4.43 MHz (PAL)) and the AD722’s on-chip oscilla- tor generate the necessary subcarrier clock. The AD722 also ac- cepts the subcarrier clock, which can be derived from an external crystal or the chip’s on-chip oscillator.
