• Manufacturer Part Number: cxa1992br
• Description: Rf Signal Processing Servo Amplifier
• Manufacturer: Sony Electronics

The ISET pin is used to connect external resistance. This external resistance sets the current which
determines the focus search, track jump, and sled kick heights.
• Focus search current
• Track jump current (TM3 and TM4 current)
• Sled kick current (TM5 and TM6 current, when D1 = D0 = 0 during 1X$ commands)
Use external resistance of between 30k to 240k .
Using external resistance outside this range may cause oscillation.
