CXD2598Q
CD Digital Signal Processor with Built-in Digital Servo and DAC
Description
The CXD2598Q is a digital signal processor LSI for
CD players. This LSI incorporates a digital servo,
digital filter, 1-bit DAC and analog low-pass filter on a
single chip.
Features
All digital signal processing during playback is
performed with a single chip
Highly integrated mounting possible due to a built-
in RAM
Digital Signal Processor (DSP) Block
Playback mode supporting CAV (Constant Angular
Velocity)
Frame jitter free
