CD-ROM Decoder with Built-In ATAPI (IDE) and DVD
ECC Interfaces
Overview
The LC897194 provides CD-ROM functionality and
includes built-in DVD ECC and ATAPI (IDE) interfaces.
Function
• CD-ROM ECC functionality, an ATAPI (IDE) interface
(the register and other blocks), and a DVD ECC
interface
Features
• ATAPI (IDE) interface
• DVD ECC interface
• Supports up to 12×-speed playback (when using 70-ns
16-bit data path DRAM)
• Transfer rate: 16.6 MB/s (when using 60-ns 16-bit data
path DRAM)
• Transfer rate: 8.33 MB/s (when using 70-ns 8-bit data
path DRAM)
• Between 1 and 32 Mbits of DRAM can be used as buffer
RAM.
• The user can freely set up the CD main channel and the
C2 flags in buffer RAM.
• Built-in batch transfer function (function for transferring
the CD main channel and the C2 flags in one operation)
• Built-in multiple transfer function (function for
automatically transferring multiple blocks in a single
operation)

Recommended Oscillator Circuit Example
R1 = 120 kΩ
R2 = 47 Ω
C1 = 30 pF
With a crystal with a resonant frequency of 16.9344 MHz, or:
R1 = 3.3 kΩ
R2 = None
C1 = 5 pF
With a crystal with a resonant frequency of 33.8688 MHz.
If third harmonics are a problem in the 33.8688-MHz recommended circuit, consult with the manufacturer of the crystal
for exact component values, since those values will be influenced by the printed circuit board used.
