TQFP64 10x10x1.4 mm (Thin Quad Flat Package) ORDER CODE: STV2310SD/SDT TQFP64 14x14x1.4 mm (Thin Quad Flat Package) ORDER CODE: STV2310D/DT
The STV2310 is a high-quality front-end video circuit for processing all analog NTSC/PAL/SECAM standards into a 4:2:2 YCrCb digital video format ,as well as conventional analog RGB or YCrCb signals. The STV2310 is programmable through an IC interface. The STV2310 provides a cost-effective solution for digitized TV, LCD TV/monitors, digital TV, STB, video surveillance/security, video conferencing, video capturing devices and PC video card. It can be used as a stand-alone chip working with third-party products, as a companion chip to the TV processor STV3500, STV3600 for digitized 100-Hz/ ProScan CRT TVs, or as a companion chip to the TV processor STV3550 for LCD-TVs.
