SANYO LC895195 Datasheet

Overview

The LC895195 is a CD-ROM decoder LSI that includes
both an on-chip IDE interface that was developed jointly
with Western Digital and an on-chip subcode ECC
function.

Features

• ATA-PI (IDE) interface

• Supports 16× playback (with IORDY) - Using ×16 70 ns

DRAMs

• 16.6 MB/s transfer rate: Using ×16 70 ns DRAMs

• 8.33 MB/s transfer rate: Using ×8 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,
C2 flag and subcode areas in buffer RAM.

• Batch transfer function (function for transferring the CD
main channel, C2 flag and subcode 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.
