Description
The CXD2510Q is a digital signal processor LSI for
CD players and is equipped with the following functions.
Wide frame jitter margin (±28 frames) due to a built-
in 32K RAM
Bit clock, which strobes the EFM signal, is
generated by the digital PLL
EFM data demodulation
Enhanced EFM frame sync signal protection
Refined super strategy-based powerful error correction
C1: double correction, C2: quadruple correction
Quadruple-speed, double-speed and variable pitch
playback
Noise reduction during track jumps
Auto zero-cross mute
Subcode demodulation and Sub Q data error
correction
Digital spindle servo (built-in oversampling filter)
16-bit traverse counter
Asymmetry compensation circuit
Serial bus-based CPU interface
Error correction monitor signals are output from a
new CPU interface.
Servo auto sequencer
Fine search which performs high-precision track
jumps
Digital audio interface output
Digital level meter, peak meter
Bilingual compatible

The V
DD
(min.) for the CXD2510Q varies according
to the playback speed and built-in VCO selection.
The V
DD
(min.) is 4.50 V when high speed VCO
and quadruple-speed playback are selected
(variable pitch off). The V

When the internal operation of the LSI is set to
normal-speed playback and the operating clock
of the signal processor is doubled, double-speed
playback results.
2
When the internal operation of the LSI is set to
double-speed mode and the crystal oscillating
frequency is halved in low power consumption
mode, normal-speed playback results.
