The TW9960 is a low power NTSC/PAL video decoder chip that is designed for video surveillance applications. It consumes very low power in a typical composite input application. The available power down mode further reduces the power consumption. It uses the 1. 8V for both analog and digital supply voltage and 3. 3V for I/O power. A single 36MHz crystal is all that needed to decode all analog video standards.
