2 GENERAL DESCRIPTION
CDR60 is a channel encoder/decoder for
CD/CD-R/CD-RW/CD Audio Recorder systems. It
incorporates all logic and RAM required for the complete
encoding and decoding processes.
There are two main datapaths through the CDR60 device.
The decode datapath captures the incoming EFM data
stream via the HF ADC and AGC functions.
The bit detector recovers the individual bits from the
incoming signal, correcting asymmetry, performing noise
filtering and equalisation, and recovering the channel bit
clock using a digital PLL. The demodulator converts the
EFM bits to byte-wide data symbols, before passing them
onto the decoder for subcode extraction, de-interleaving
and error correction. The decoded data is then made
available via the multi-function serial output interface.
The encode datapath takes data symbols from the block
encoder/decoder via the serial data and subcode input
functions, encoding them via the encoder block. The
encoded data stream is passed to the EFM modulator,
which generates the required EFM signal, output as a
digital bit stream. The encode process is controlled via the
Wobble processor, encode control and EFM clock
generator functions.
As well as these two data processing sections, three
further blocks support overall device operation. The
system clock generator provides all digital clocks required
by the CDR60. The motor servo allows the CDR60 to
control the spindle motor and is controlled by the
microprocessor interface. This interface can be accessed
either via a parallel (80C51) or a serial (I2C-bus) interface.
