CD-ROM Error Correction LSI
with On-Chip ATA-PI (IDE) Interface
LC895194
Functions
CD-ROM error detection and correction, ATA-PI (IDE)
interface (including the register and other blocks)
Features
• ATA-PI (IDE) interface
• Supports 16×-speed playback (with IORDY): Using 16×
70 ns DRAMs
• 16.6 MB/s transfer rate: Using 16× 70 ns DRAMs
• Supports the use of from 1 M to 32 M of buffer RAM.
(DRAM)
• Allows the user to arbitrarily set the CD main channel
and C2 flag areas in buffer RAM.
• Batch transfer function (function for transferring the CD
main channel and C2 flag data in one operation)
• Multi-transfer function (function for sending multiple
blocks in one operation)

Sample Recommended Oscillator Circuit
R1 = 120 kΩ
R2 = 47 kΩ
C1 = 30 pF
For a crystal oscillator frequency of 16.9344 MHz.
Alternatively:
R1 = 3.3 kΩ
R2 = None
C1 = 5 pF
For a crystal oscillator frequency of 33.8688 MHz.
For an oscillator frequency of 33.8688, the third harmonic is used. This means that
precise component values will be influenced by the printed circuit board. Consult
the manufacturer of the crystal to determine the circuit constants for this frequency.
