75/110 ohms

PCB 8285-B
Open Leads 8285-A
 Open lead package PCB Package
APPLICATION Isolating transformer for conversion of nominal 110 ohms balanced digital signals to nominal 75 ohms unbalanced and vice versa. Enables 110 ohms balanced devices to be used with of 75 ohm coaxial cable and/or 75 ohm distribution systems.
FEATURES 110 ohm balanced winding is centre tapped (ct) so it can be grounded to case via a capacitor for EMC purposes. Small size permits enclosure in a 16mm diameter tube for use with XLR/BNC connectors etc. PCB or open lead versions available.
RATIO 1.2ct:1
BANDWIDTH 0.1 to 6 MHz
MAXIMUM LEVEL 5 V P-P
INSERTION LOSS Less than 0.3 dB
VSWR Less than 1.1
 APPLICATION NOTE Leads should be twisted to minimise impedance discontinuity when using XLR/BNC connectors. PCB tracks should be laid out so they act as far as possible as 110/75 ohm transmission lines (i.e close parallel tracks)
CONNECTIONS 8285B connections
