The Selenio™ SEL-DDA1-xxx provides multiple functions. Conversion from SDI (270 Mb/s) to analog composite (dual channels) adds NTSC/PAL and PAL-M outputs to the Selenio platform. The DDA can be used as a single / dual distribution amplifier, small routing switcher SDI / ASI and electrical <> fiber optic converter. If placed beside a Selenio frame sync (FS) or conversion (XD), the DDA may be used as a VEX video expansion module. The DDA may be placed in any open Selenio slot and has its own block diagram User Interface.
