BIT1201G
Digital Video Encoder
BIT1201G provides conversion from digital video formats YCbCr or YUV into NTSC and PAL composite analog video. Input for masters can be 27 MHZ 8-bit YUV, 8-bit YCbCr, or ITUR.BT656 with support for EAV/SAV codes. Video output can be formatted to be compatible with PAL B/D/G/H/I and NTSC-M systems. Closed Caption is supported in NTSC/PAL both. One high performance of linear 8-bit current DAC provides composite or Y or C output.
