SANYO LA9605W Datasheet
Ordering number : EN5980
D2598RM (OT) No. 5980-1/11
Overview
The LA9605W integrates MiniDisk playback functions,
including servo error signal generation, RF signal
processing, and wobble signal binarization output on a
single chip. The LA9605W, when combined with an
LC89640, can implement a complete MD player system.
Features
• Allows the servo error signal level to be set to an
arbitrary level using a VCA circuit.
• Few peripheral components required.
• Ultraminiature package
Functions
• Servo signal I-V conversion amplifier
• Pit/groove switching RF amplifier
• RF equalizer amplifier
• Servo signal VCA
• APC circuit
• Focus error amplifier
• Tracking error amplifier
• HFL circuit
• Defect detection circuit
• ADIP amplifier
• Pre-pit circuit (pit/groove discrimination circuit)
• ADIPCR
