AD725 Datasheet Low Cost RGB to NTSC/PAL Encoder with Luma Trap Port

Manufacturer: Analog Devices

General Description

The AD725 is a very low cost general purpose RGB to NTSC/ PAL encoder that converts red, green and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards.

These two outputs are also combined on-chip to provide a composite video output.

All three outputs are available separately at voltages of twice the standard signal levels as required for driving 75 Ω, reverse-terminated cables.
