BC350 Distribution Amplifier HD-SDI, SD-SDI, ASIpdf

The BC350 is a distribution amplifier for the distribution of HD-SDI, SD-SDI and ASI signals in a digital television facility. The incoming signal is auto-sensed and then equalised prior to being driven into the five available outputs. Careful attention has been paid to reduce thermal runaway, eliminating the need for forced air cooling as fan failure and overheating is the most common cause of failure in modern electronic systems.

In non-reclocking mode the unit can operate with data rates from 10 Mb/s to 1.5 Gb/s.

The BC350 occupies a single slot in the BC100-3RU 19" rack-mounting frame which can hold up to 15 single slot cards. Some BC Series processing cards have dual functionality allowing up to 30 channels of video to be transmitted or received from a single 3RU frame.
Signal and card monitoring is achieved through SNMP monitoring in the BM101 network card.
Alternatively GP-Output alarms can be triggered via the BM100 module.

For stand alone applications the BC350 can be housed in an individual rugged enclosure.
