SW221 3G

What is it?

SW221 3G 3G/HD/SD routing switch3G/HD/SD 2 x 2 routing switch.

Reason to choose it...

It's a cost-effective solution for simple 2 x 2 switching when you're using 3Gb/s, HD or SD sources. Either manually switch at the appropriate point in the vertical blanking for minimal distribution or make it an auto changeover switch and set it to automatically switch on missing input, invalid signal or invalid format. You can use the programmable delay to ensure you've definitely got a stable input before you switch back, and even opt for relay bypass protection to prevent signal loss for that extra peace of mind.

Ideal for...

Any 3Gb/s, HD or SD simple switching application where minor disruption to the output doesn't matter – such as before other processing equipment or before an MPEG encoder which is protected by a synchroniser.

Reliable and cost-effective switching

The SW221 3G provides simple 2 x 2 switching between two 3Gb/s, HD or SD signals, making it ideal for use either as an emergency transmission switch to avoid broken equipment or to manually bypass products requiring maintenance on a 24 hour station.

Where a single point of failure is involved you need something that you know will always work. Broadcasters choose the SW221 3G because of its functionality, its price and because they trust it for this critical task.

Triggering the switch

The SW221 3G is ideal for switching between the main and backup feeds of a television station, and offers independent control of the two outputs.

With manual switching there is the choice of switching between the two feeds either immediately or in the vertical blanking period, with the SW221 3G detecting the video standard and switching at the appropriate point to enable a cleaner switch.

It can also be used as an auto changeover switch. An automatic switch away from a faulty source is triggered immediately on loss of input or invalid video, determined by loss of the sync word structure. A single format can be set as valid, allowing the SW221 3G to automatically switch away from inputs that are legal but not the correct format.

Choose when to switch back

Switching back can either be automatic or by user intervention.

When set to automatic the board will switch back if the original input returns to a valid state, with a programmable delay ensuring that the previously faulty input remains good for the selected time period.

When set to user activated it will stay on the new selection until the routing is changed by the operator, or the new input becomes invalid.

Get multiple outputs of your switched signal

The SW221 3G provides two outputs of the first switched signal, along with one output of the other – with the secondary signal output ideal for previewing both the main and the backup feeds.

Save rack space - and protect your output

Crystal Vision frameThe SW221 3G will save you rack space, with this 100mm x 266mm module fitting in Crystal Vision’s standard frames and allowing easy integration with any products from the range.

The inputs and outputs are accessed by using the RM53 and RM54 frame rear modules. The RM54 includes relay bypass protection on power failure or board removal, giving that extra layer of security and preventing signal loss.

Choose your control

SW221 3G’s flexible control options give you the choice of board edge switches, front and remote panels, SNMP, GPIs and PC software.

VIDEO INPUTS

Two 3Gb/s, HD or SD inputs (1 and 2)

Input return loss: - 15dB for 50MHz to 1.5GHz

Auto 50/59.94/60Hz and video format selection

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 259, SMPTE 292-1 and SMPTE 424/425-A. 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

What outputs do I get?

Signal inputs and outputs are accessed by using an appropriate rear module.

The rear modules slot on to the back of the frame and typically feature BNC, D-Type, 'easywire' DIN 41612, RJ45 and optical connectors. The single and double slot rear modules can be used with all three frame sizes, while the quad slot rear modules just fit the 2U frames.
