AD8131 AD8130 have considerable cost performance improvements over discrete driver receiver solutions. AD8131 differential single-ended input differential output driver requiring external components fixed gain AD8131 unique internal feedback feature that provides output gain phase matching that balanced -60dB 10MHz, providing high quality video signal distribution while minimizing both radiated susceptibility. output common-mode voltage, voltage input VOUT REF. AD8131 driver capable driving either cat.3 cat.5 twisted pair coax with minimal line attenuation. AD8130 differential single-ended receiver work with AD8131 driver. AD8130 excellent common-mode rejection allowing cost unshielded twisted pair cables without fear corruption external noise sources cross-talk. Active feedback been incorporated internally improve overall system performance. AD8130 user adjustable gain help compensate losses transmission line. output provides capability drive 50mA with high capacitive loads.

SETTING COMMON MODE VOLTAGE
common-mode voltage, VOUT REF, driver/receiver pair either driver receiver side. figure VOUT directly drive side mid-supply rails, voltage level that does violate common-mode voltage range specification VOUT avoid signal distortion, consideration common-mode voltages differential signal swing important that input output voltage swings both driver receiver violate voltage input output range specifications. Figure shown with twisted pair cable, however this configuration also used coax cable.
