STV0117 - ST Microelectronics

STV0117 Pal / Ntsc Digital Encoder

The STV0117is a digital video device implemented in pure CMOS technology for multimedia, digital TV and computer applications. The STV0117converts the digital output of a Video MPEG Decoder into a standard analog baseband NTSC/PAL signal with color subcarrier modulation. The STV0117 can handle interlaced mode (with 525 or 625 line standards), or non-interlac.
