Overview

Support is limited to customers who have already adopted these products.

The TW9920 is a multistandard video decoder and encoder chip that is designed for multimedia applications. This low power, integrated solution has a 4H comb filter based NTSC/PAL/SECAM video decoder that converts analog CVBS or S-Video signals into digital YCbCr output. The integrated analog video encoder converts digital YCbCr inputs into analog CVBS or S-Video output.
