Overview

The dedicated RF-amp was introduced with the PU-18 motherboard, after the Servo controller has been integrated into the DSP. Before PU-18, a Servo-controller/RF-amp combo IC was used (CXA1782BR).

Revisions

  • CXA1791N (PU-18)
  • CXA2550N (PU-20)
  • CXA2575N (PU-22 and up)

The marking on these ICs omits the "CX" prefix; hence the text on them says A1791N, A2550N, A2575N.
