Dual Zo Digital Audio Transformers combine 75 AND 110 Ohms Zo: AES/EBU, AES-3id, SP/DIF We have developed two SMD transformers designed to interface both balanced and unbalanced connections, by use of dual windings of different ratios. Both of these parts provide High CMRR, Lowest Jitter, Low Interwinding Capacitance, while reducing the PCB footprint and component count. Both have the same footprint as our other SMD parts. SC939-06LF 110 Ohm Balanced to 110 Ohm Balanced and 75 Ohm Unbalanced  Scientific Conversion SC939-06LF is a shielded 1.2 : 1.2 : 1.0 ratio dual secondary low profile surface mount AES/EBU transformer. SC939-06LF is designed for Studio, Broadcast and Professional applications for transmit or receive applications where both balanced 110 Ohm and unbalanced 75 Ohm outputs or inputs are required. These ratios couple a 110 Ohm primary to both 75 and 110 Ohm secondaries. SC939-06LF is designed for use with all popular AES/EBU transmitters, receivers and transceivers, at sample rates from 28 kHz up to 192 kHz. SC939-07LF 75 Ohm Unbalanced to 110 Ohm Balanced and 75 Ohm Unbalanced Scientific Conversion SC939-07LF is a shielded 1.0 : 1.2 : 1.0 ratio dual secondary low profile surface mount AES/EBU transformer. SC939-07LF is designed for Studio, Broadcast and Professional applications for transmit or receive applications where both balanced 110 Ohm and unbalanced 75 Ohm outputs or inputs are required. These ratios couple a 75 Ohm primary to both 75 and 110 Ohm secondaries. SC939-07LF is designed for use with all popular AES/EBU transmitters, receivers and transceivers, at sample rates from 28 kHz up to 192 kHz.
