The XM650 balun add-on card demonstraons DAC to ADC loopback with a 16T16R
conguraon of N79 baluns and lters. There is no external connecvity to the ADC or DAC
signals. Digital IO and I2C are supported on headers.
Following are the features of XM650 module:
○ 16 DAC outputs looped back to 16 ADC inputs
○ 32 N79 baluns and lters on the card
- B46 or N77 band baluns can be supported with BOM change or re-work by customers.
○ 20 DACIO digital I/O pins on a header strip
○ 20 ADCIO digital I/O pins on a header strip
12V, 5V0, 3V3, VCCADJ DAC, VCCADJ_ADC, DAV_AVTT, and GND access on a header strip.
