CD Digital Signal Processor
Description
The CXD2500BQ is a digital signal processing LSI
designed for use in compact disc players. It has the
following functions:
• Wide-frame jitter margin (±28 frames) realized by a
built-in 32K RAM.
• Bit clock generated by digital PLL for strobing EFM
signals. Capture range of ±150 kHz and over.
• EFM data demodulation
• Enhanced protection of EFM Frame Sync signals
• Powerful error correction based on Refined Super
Strategy
Error correction C1: Double correction
C2: Quadruple correction
• Double-speed playback and vari-pitch playback
• Reduced noise generation at track jump
• Auto zero-cross muting
• Subcode demodulation and subcode Q data error
detection
• Digital spindle servo system (incorporating an
oversampling filter)
• 16-bit traverse counter
• Built-in asymmetry correction circuit
• CPU interface using a serial bus
• Servo auto sequencer
• Output for digital audio interface
• Built-in digital level meter and peak meter
• Bilingual
Features
• All digital signals for regeneration are processed
using one chip.
• The built-in RAM enables high-integration
mounting.

∗1 VDD value of 4.75 V (min.) is for the double-speed playback mode at vari-pitch control reset. For the low
power consumption special playback mode, VDD value is 3.6 V (min.). ∗2 In the normal-speed playback
mode VDD value is 4.5 V (min.)
∗2 Low power consumption, special playback mode
Set the internal operation of LSI at the double-speed mode, and half the crystal oscillation frequency. This
will result in the normal-speed playback mode.
∗3 VDD value of 5.25 V (max.) is for the double-speed playback mode at vari-pitch control reset. For normal-
speed playback and the low power consumption special playback mode, the VDD value is 5.5 V (max.).
