4 VSI - Video Synchronization Input Card
4 VSI - Video Synchronization Input Card
Video signal input module
The VSI (Video Synchronization Input) card provides video signals to an IMS clock module as reference. It can
process Black Burst (PAL), LTC (Linear Time Code) and programmable Word Clock Rates.
Connectors: 4 x BNC female
Reference Inputs: Video Sync In
Black Burst (PAL SMPTE259M/ITU-R BT.470-6)
Input with VITC reader (SMPTE12M-1/SMPTE ST309M)
Black Burst (PAL) Input with Prescaler mode
(no VITC, frequency only)
LTC In
Linear Time Code LTC Reader (25 FPS as per SMPTE ST12)
Word Clk In
Word Clock Input with programmable frequency range
PPS In
1PPS input
Power Requirements: 5 V, +-5%, 300 mA
Status Indicators
LED St: VSI status
LED In: Status of the backplane’s reference signals
LED A Status of the input signals (1 & 2) at the board
LED B: Status of the input signals (1 & 2) at the board
Operation conditions:
Initialisation: LED St blue until configuration is done
LED In off until configuration is done
LED A off until configuration is done
LED B off until configuration is done
expiration LEDs: ALL LEDs 0,5 sec. red → 0,5 sec. yellow → 0,5 sec. green → 0,5 sec. off
Normal Operation: LED St / In green
LED A green, if Video Sync In and LTC In
flashing green, if only Video Sync In
flashing yellow, if only LTC In
off, if no signal
LED B green, if Word Clk In and PPS are available
flashing green, if only Word Clk In is available
flashing yellow, if only PPS is available
off, if no signal
