CXA1992 SONY [Sony Corporation], CXA1992 Datasheet - Page 25

• Manufacturer Part Number: CXA1992
• Description: RF Signal Processing Servo Amplifier
• Manufacturer: SONY [Sony Corporation]

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 30kΩ to 240kΩ.
Using external resistance outside this range may cause oscillation.
