Allen Avionics HD-VIT-75
The Allen Avionics HD-VIT-75 Video Isolation Transformer eliminates hum in HD-SDI transmission lines. It provides electrical isolation between the input and output and also eliminates induced currents in long cable runs. This device is useful for broadcast systems where hum is present due to ground loops or where there are large differences in ground potential.
Supports all transmission rates of SMPTE259m and SMPTE292m up to 1.5 Gbps HD-SDI video input
Equivalent to less than 20 ft (6 m) of cable
Isolated signal path
Greater than 60 dB of ground loop isolation
Passive device -- no power required
Small cylindrical package with gold-plated BNC connectors for better response
75 Ohms balanced with 3.0 GHz bandwidth
Greater than 15 dB return loss till 1.5 GHz
2 kV flash tested
