Description: The TW9990 is a low power NTSC/PAL/SECAM video decoder chip that is designed for automotive applications. It supports both single-ended and differential composite video as well as S-Video. Typical power consumption is 110mW for composite input applications, and the available power-down mode further reduces power consumption. It uses 1. 8V for both analog and digital supply voltage and 3. 3V for I/O power. A single 27MHz crystal is all that is needed to decode all analog video standards. The video decoder co
