The XM755 balun add-on card uses the 8 x 50 x 2 female LPAM-50-01.0-L-08-2-K-TR connectors and pinout as defined in XM650/755 Connector Pinouts. For signal break-out Carlisle CoreHC2 connectors and cable assemblies are used. Digital I/O and I2C are supported on headers.
The XM755 module features are:
- 16 ADC differential signals to 4 male Carlisle CoreHC2 connector pads
- 16 DACs differential signals to 4 male Carlisle CoreHC2 connector pads
- 2 ADC inputs – compression mount SMAs through low frequency baluns – Minicircuits TCM2-33WX+
- 2 ADC inputs – compression mount SMAs through mid frequency baluns – Anaren BD1631J50100AHF
- 2 ADC inputs – compression mount SMAs through high frequency baluns – Anaren BD3150N50100AHF
- 2 ADC inputs - compression mount SMAs through high freq baluns – Anaren BD60120N50100AHF
- 2 DAC outputs compression mount SMAs through low frequency baluns – Minicircuits TCM2-33WX+
