TW9990: NTSC/PAL/SECAM Decoder Reduces BOM and Enhances Performance
The TW9990 is a low power analog video decoder that supports NTSC/PAL/SECAM single-ended, differential, and pseudo differential composite video inputs as well as S-Video. A single 27MHz crystal is all that is needed to decode all analog video standards. Typical power consumption is approximately 100mW for composite inputs. A power-down mode further reduces consumption. The TW9990 video decoder eliminates the need for the external op amp and the associated cost, as it supports differential composite video signals directly, and has built-in programmable short-to-battery and short-to-ground detection.
