SD-SDI Frame Sync Module

The SFS6860N is an SD-SDI frame synchronizer, which can synchronize with one genlock reference signal and can provide one audio synchronization signal (DATA I/O) for an audio processing module. It can work in both the synchronization and delay mode, supporting adjustable delay which is less than one frame. It supports both forced black field output and forced freeze frame; which are controlled by GPI, and retains the ancillary data of the signal source and supports one channel of analog composite video output.

• Forced black field output and forced freeze frame output controlled by GPI
• Delay and synchronization mode

• Detection of the input video loss, freeze frame and black field
• Support manually controlled freeze frame and black field
• Adjustable horizontal and vertical phase
• 4 Channels Embedded audio monitoring
• Embedded Audio loss and overshoot monitoring
• Detect the compatibility between reference signal input and SDI input
