The CL-CS3712 is Cirrus Logic’s high-integration, high-
performance ATAPI DVD drive manager. It integrates all
required components for a DVD loader for DVD players,
game consoles, and DVD-ROM drives. The CL-CS3712
includes an RF amp, servo control processor, data
channel, DVD ECC, CSS authorization, CD-ROM
decoder, and ATAPI interface.
The CL-CS3712 can be configured with an audio DAC
(digital-to-analog converter), external buffer memory (8- or
16-bit DRAM), a local micro-controller with its RAM and
ROM, and power drivers to create a complete DVD-ROM
electronics solution.
The CL-CS3712 supports DVD disc speeds up to 8x and
Ultra DMA host speeds up to 33.3 Mbytes/sec.
The RF signal is over-sampled by a high-speed ADC
(analog-to-digital converter). The timing loop is closed in
the digital domain with variable decimation and
interpolation used to provide the output samples to the
data recovery logic. A channel-quality logic circuit is
provided to allow parametric calibration.
The CL-CS3712 data channel supports partial response
maximum likelihood (PRML) data acquisition, providing
state-of-the-art data recognition in a noisy environment,
coming from the pick-up head.
