Here is some additional info from the manufacturer

The SYNC HD from Avid is a master clock that can keep even the largest Pro Tools HD and audio-video productions in total sync. The unit attains near sample-accurate lock to serial Timecode (through RS-422), LTC, or bi-phase/tach signals. It incorporates a high-fidelity, low-jitter master Wordclock that supports operations up to 192kHz, as well as standard pull-up/pull-down rates for film and video applications. 

SYNC HD also features AES/EBU clock I/O, SD and HD video reference in/thru, video program in/out with Timecode window inserter, and a host of other features, making it an indispensible addition to any Pro Tools HD system utilized by professionals in commercial music and post-production facilities.
