VIDEO OUTPUTS
Two independent ports with two outputs of the first input and one output of the second using RM53 and RM54 frame rear modules
270Mb/s or 1.5Gb/s or 3Gb/s serial compliant to EBU 3267-E, SMPTE 259M, SMPTE 292M and SMPTE 424M. Output follows the input format
The RM54 frame rear module provides relay bypass protection. An electromechanical relay switch needs power to hold the switch in one state and will revert to the other state (board bypass) on loss of power. It prevents signal loss by mechanically connecting input 1 of the SW221 3G to its main output 1 on complete frame power failure or board removal

DELAY THROUGH BOARD
10us max

SWITCHING
The switch timing can be either immediate or timed and will apply to both outputs
Timed switching as defined in SMPTE RP168-2002 or immediate switching if input missing
A timed switch will occur in the correct time period according to the reference input (input 2 if valid)
The outputs of the switch can be configured to automatically switch away from a missing input or non-valid signal. A single format can be set as valid, so that the SW221 3G automatically switches away from inputs that are legal but not the correct format
The SW221 3G can be set to switch back automatically or by user intervention
Automatically: the board will switch back if the original input returns to a valid state. A programmable delay can be added to ensure the previously faulty input remains good for the selected time period
User intervention: if the board auto switches away from an invalid input it will stay on the new selection until the routing is changed by the user, or the new input becomes invalid
