IQSYN11
3G/HD/SD-SDI Dual-channel Frame Synchronizer
The IQSYN11 provides frame synchronization for HD-SDI at 3 Gb/s or 1.5 Gb/s, or SD-SDI 270 Mb/s. Includes dual-channel independent SDI input processing functionality and agile synchronization. A video proc amp provides complete control over the video levels. The IQSYN11 is a space-efficient low-cost solution that includes core functionality.

FEATURES
