Video converter for multi-standard display inputs
The Intersil/Techwell TW8809-NA2-CR is a video converter IC designed for video display applications, accepting composite and S-video inputs in NTSC, PAL, and SECAM formats and converting them to digital output compatible with ITU-R.656. It operates from dual supply rails of 1.8V and 3.3V, with control via an I²C interface, making it straightforward to integrate into existing digital video pipelines.
It is ROHS3 compliant, which simplifies compliance for EU and global markets.
Package and thermal considerations for layout
The 56-VFQFN exposed-pad package (supplier device package 56-QFN, 8x8 mm) requires a solid ground-plane connection and a grid of thermal vias under the pad to keep junction temperatures within limits during full-rate video conversion.
